Okay, basically I am just going to lay this all on the table! Maybe a tad bit scattered

Every since I was little I had a sense of things, before they would even happen, my mom chalked it up to a "good guess" always had different feelings then others and often very rare dreams.. now.. we moved into my house ( which I live in the basement apartment now with my daughter ) and we know its haunted, but he's not a threat, only when we first moved in or house renos seems to spark things. Now.. a few weeks ago I had a very weird dream that had some weird paranormal in it with a spirit opening draws shutting doors and scaring my daughter it woke me up right away. Then I started to get sick. Headache, fever, had a spinal tap done, they said the flu.. came home that night.. laid in bed and had what I thought was a dream,. you know how to can see gas waves, it looked like that all over me.. and I was having a seziure type of shaking and was trying to reach for my phone. It was odd. I didn't know if it was real or not but felt like someone was attacking me.. now for the past few years, I can hear my apartment door open, someone walking in and standing at the edge of my bed staring.. whispers.. my name.. I am usedd to this now.. well my headaches are far worse, happens in a few spots near my bed, likea brain freeze times 100.. for a few seconds.. last night when I was in bed.. I hear snarling and grunting.. which was very uneasy.. does this sound crazy yet?. this seemed different then before, I am used to seeing shadows and whispers but never grunting or snarling.. sounded like an animal.. what do I do about this.. people think I am going nuts, I am even booked for an MRI in two weeks.. and I had an EEG.. which was abnormal.. left side was slow waves, getting worried here.. any thoughts

Firstly I'm not a sceptic regarding the paranormal, I have had enough experiences to accept that things really do happen which cannot be explained.

However, with the particular health problems you are having I am wondering about electromagnetic fields. These have been shown to cause both health problems like the ones you are suffering from in susceptible people and to cause hallucinations. Several experiments have now been done which show it is quite possible to induce weird hallucinations by exposing the brain to certain electromagnetic patterns. I have heard of people who have had similar problems to yourself and have solved them simply by moving electirical equipment and/or their bed. Even an electric alarm clock turned out to be the culprit in one case.

So my first step would be to have a look around your sleeping environment and remove any eletrical items. Wi-fi, cordless phones, computers, tvs, etc. It may be that even if there are not in your actual bedroom you are subjected to them from an adjacent room. Moving the bed may be necessary.

I'm not suggesting that some of your experiences haven't been real but in my experience the sort of people who are sensitive to the paranormal often have unusual sensitivities to more normal things too.

Do keep up with the medical checks as well though.

From the sounds of things it looks like its going to come down the a physical cause. When having the flu if your tempreture goes high enough it can cause all sorts of things to happen. Even seziures. SO best to wait until after getting fully checked out before making further comments. Another thing you need to do is start recording and keeping a diary of events and look for patterns as well as see if you catch anything on recorder.
