Okay so this is going to bereally really long and just about every detail I remember is in here so bare with me. But its been in my brain all day since I woke up from having it this morning. The guy in the story is actually a guy that has wanted to go out with my for three years. I am really starting to like him now but this dream gives me the impression I'm too late. He also has not had a girlfriend. So I'm like the only one he's really liked. Here it goes.
I was at some kind of party or something. It was a very large 2-story house with enormous bathrooms. I wanted to take my makeup off and re-apply it so it looked good. Well I didn't get a chance too. So I went (makeup less) into a very large dark room with black walls and those colorfull lights you see at the skating ring. There was this little partially closed off hidden part of the back corner of the room and will was sitting on a brown leather couch. (the exact one that's in my room)Well I wanted to put some makeup on before going to say hi. (wouldnt any girl naturally want to? Lol) well something was stopping me. I forgot exactly what but there were these 2 people trying to chase me and hurt me. One girland one guy. Both teenagers. I didn't get to put on any makeup. Then all of a sudden we were at a waterslide amusement park. I walk up to will and saw him with a girl. He said it was his girlfriend. (sadness washed over me) She was pretty but he had to choose between us. He picked me. Th girl shortly disapeered. Then I am all the sudden back in the parking lot in my moms car. I tell her I have to pee or go inside for something. She tells me not to go into the big bathrooms or to keep the light off. (she is afraid something bad will happen to me.) I run inside the house and the two teenagers are at a counter with a white blender. They look up and try to catch me. Somehow I distrackded them long enough for me to run up the stairs and ran up to the big bathroom. (it was kind of fuzzy on what happened next I don't really remember but I think will was with me it may have been some other guy.) I never had to pee I just ran inside to see him. Well I end up back in the parking lot and we are together. (hes wearing a white shirt) his mom is calling him from their car (which is also white) we hug for what seems forever. I start to feel really strong emotions for him (which have lasted all day so far) and when I dtop hugging him I see blood on my hands but it came from him. His arm was covered in blood and was coming off or something and he had blood all over his body. He stepped back (I think he either might be smiling or no emotion at all) and everything goes black and I wake up to my sisters fighting.
So this was very long and to everyone/anyone who read it I thank you. I know it was very desciptive and a little confusing. If you could give me your feedback on what youthink it means I would be very grateful. I think it has multiple meanings (because of the people trying to chase me, then will covered in blood, them him with a girlfriend. Idk) thank you!

Now details in dreams are symbols, and not necessarily directly. Going with each detail from the dreamer's subconscioius you must consider the feelings and emotions of the detail in waking and sleeping life, and what it could represent, and how it affects or causes other things in the dream. First off, it starts with your desire to put on makeup, and failing. You must have been a bit anxious through that detail. Makeup may not literly mean the makeup you normally wear. It could mean you're trying to hide a feeling but you can't, or it may not even have to do with covering in particular, it could mean you want to prepare your senses [eyes] - oh and where were you putting makeup on your eyes or face skin? - . You obviously like wearing makeup to feel normal and confident, so it must be a normal thing to do awake. It could represent a change , because you were not able to do what you normally do, putting on makeup, or you may be anxious due to a sense of not being able to recognize the familiar. Moving on, the room is black and in a corner there is a leather armchair. How do you feel about that object or how does it relate to you in your life when awake? It may represent comfort, security, familiarity, or being yourself, maybe yourself [personality or feelings] being put in a new setting, like seeing soemthing in a different setting [the chair in this dark corner instead of bedroom] may make your feelings change, or make you desire to think about soemthing. The fact that this character [will] in your dream is in the chair could represent a number of things. But also, as objects and even places may not directly represent those objects or places [ a TV in a dream may not just mean a TV it may be symbolic and not literal], the people in dreams may not specificially represent those people that you know from your waking life. How you feel about him in life and the dream and what happens to him and how it affects your mind must be considered. He could represent a characteristic about him, is he comforting, or maybe your feelings for him in the dream seem out of place compared to how they are in real life. Before interacting with this character, you wanted to put on makeup, but something stopped you. Then you were being chased... this could represent stress, anxiety, slight fear, or a response to the incident before it being you going to say hi to him. At the waterslide, you saw him with another girl. What color was the waterslide, and was it straight or spiraling? Was this dream in the daytime or nighttime? The waterslide could represent the "flow" of your feelings and your control over them, in general or relating to what this character [will] in the dream represented [see above]. I've noticed these events happen in public places which seems interesting. In your life, outside of the dream, what is the significance of that parking lot - have you seen it? And what about the waterslide? You distinctly remember sadness when you found out he had a girlfriend. Maybe it displayed a feeling of [or feeling of lacking] security in your life, or maybe it represented indirect loss, or maybe --not necessarily that 'you didn't get what you wanted' [because then he already had a girlfriend who wasn't you], but now something [will the cahracter in your dream, what he represents] is not available; and depending on your personality maybe in your waking life, you like to have everything available to feel comfortable even if you don't want it then. Like always knowing you have a clock , when you don't desire to know the time.. for example.. Moving on, how did you feel when he picked you? It could represent your feelings or desire of comfort being fulfilled? You said you are "Back" in the parking lot, were you there before you went to the waterslide of the park, is it the parking lot for the amusement park? Seeing your mother in the dream may represent nurture, also comfort, maybe caution. Maybe you are afriad that without being familiar with things from your past [like if things change in your waking life] and that without security [maybe a cause or result of this change, or maybe it's a separate issue] that you have comfort which partly replaces the loss of security or comfort in a different part of your life. You see him inside, and you probably were relieved after being chased. Maybe you are stressed and are trying to find a way to relieve yourself in real life. The parking lot is recurring which may represent a number of different things. According to your description it [parking lot] is there before and after the waterpark, and has your house at it [which is in the dream twice also]. Is the parking lot empty? While you have feelings similar to those you had when Will chose you [at the slide], [and also when.. >] when he hugs you, maybe in your life you're searching for a feeling of perfection or completion or simply something permanent or comfort. A shirt could be similar to makeup since it covers and it is a normal thing in life to wear on the body ; like makeup for some people on the eyes [or face], but the shirt and makeup may be very different it depends [they may represent different things]. Maybe you see him [what he could represent] as pure and secure and "light" -which is odd, because his shirt color could represent light which is also what your mother [what she represents] told you not to turn on, just something to think about! Then he is covered in blood. You may have felt shocked, or confused in the dream. And maybe that also represents change and how you are shocked or confused about change in life. It could represent your confusion in guidance [hand] for yourself in your waking life, or that you have a damaged connection with something/someone in your life maybe?

Sorry my interpretation of your details was long, but I tried to help you!
Please take the time to read it!

Thank you so much! This really helped me a lot! I will post and answers the questions you had in the morning.(:

I wanted to put the makeup on my face not eyes. My leather couch is soft and comforting familiar and secure to me. I have had it for a while and I use to go up there and sleep on the couch while watching my dad play guitar now the couch is mine and my parents are divorced.
The waterslide was blue and spirally. I was more aware of the light blue sparkling water though. It is daytime while we are at the waterslide.
I don't think I have ever seen that parking lot before.
After the waterslide I said I went back to the parking lot I hadn't really been there before I was looking at the outside of the house. Iwasnt aware of the parking lot "before".

Continuing my interpretation.. Maybe because of a change you are trying to accomplish something, to perfect something, maybe you feel you need that to feel maximum security enough for you to be comfortable in some aspect of your life. The armchair could represent your past, and my analysis could make sense if the change is your parents divorce and the chair got put into a new setting because it was no longer in your bedroom [familiarity] but in a dark corner due to this change, like the divorce, and maybe your feelings in general are seeking personal security. The waterslide could mean complexity, or patterns, but since your focal point was on the water it could represent your focus on your emotions, and yourself control maybe relating to these emotions or maybe not relating. And if after you left the waterpark you went to the parking lot for the first time, was it inferred that you were there 'before' in the dream, or did you mean to say you were only at that setting once in the dream?
