This is interesting to me because this has been happening to me frequently as of late.
The worst of it was just the other night. I woke up from a dream in which I was just told that my cousin had died. I felt the most grief I think I have ever felt in my entire life. I woke up in tears and my girlfriend was trying to calm me down. I was freaking out by all accounts. I felt like I was dying. I was seeing things on the walls. It was crazy. I got out of bed to try and go get water, so I walked in the other room and I stopped. I could not make myself enter the room to get my glass. I started panicking and turned around and ran back into my bedroom. All the meanwhile I was completely unsure as to what was happening to me. It was freaky for sure.
I've never felt so much pain, grief, and fear as that night. It took me a half hour to calm down and then get back to sleep.
The worst part about the dream, was that I was told my cousin had died because "her brain stopped working". I also learned this as I was getting into a car to go to a soccer game... I don't play soccer nor do I think about soccer or like soccer.... but my cousin had a friend on her soccer team who died suddenly of a brain aneurysm while they were playing... It was freaky as hell. I was convinced I was about to have the same thing happen to me, or that something awful had happened to my cousin and I was about to get phone calls regarding it.
Anyways, that's my story.
