Can someone tell me what my dreams might mean! One night I had a dream I was walking down the hall at my college with my grandma she had told me my sister was dead and I was denying it because I would see and talk to my sister in my dreams. Then I had a dream where I was talking to my same sister in the bathroom I couldn't see her because she was in the stall but she was telling me she was dead and she's okay but I would cry and deny it it was like she was dead but still there.. And then I had a dream where I went to a funeral there were 3 caskets and in them there was my sister my brother and cousin they were dead but they were sitting up they started talking to me telling me they were okay not to cry. I also had one last dream where I was told my brother and cousin were dead and I spent the dream crying and searching for them. After all these dreams I would wake up crying what could this mean?

It means you are struggling with the concept of losing people you love to death, that's all. It's very common. Don't dwell on the little details because the brain mixes real events of your life all together like a whirling soup, old ones, recent ones, and creates a new movie out of them.
When I was a teen I had a recurring dream of finding my sister dead in the bathtub with stubs for arms and legs. I used to complain that she hogged the shower too much and I had made some remark about her washing her arms and legs off.
If you really wake up with tears on your face, you need to examine your inner thoughts and feelings about your family, any losses, any angry words spoken that you didn't mean, any fears about leaving home, anything that might be brewing in the back of your mind about death.
