I have dreams where i have actually died all different kinds of ways, and i actually felt the pain like you did too. i know it is most likely from my meds, as i never really brought this subject up with anyone before. I am on 8 different meds my dreams are either hilarious but mostly scarry like terrified scarry. I also dream im composing music, doing long math equations, dancing ice skating all the stuff i know i could never do in the real world. also i design dresses in my dreams too which seems funny to me because i took a sewing class and the skirt was so funny and uneven like the rest of the stuff i made in that class. Sometimes i hate waking up if i'm having a great dream which means im dreaming of an old lover i never got over. such a disappointment in some ways but i am happily married now.
