OMGGG I too, I dream something like that often and had the feeling that even when my sleeping pills were empty, it was really bad, my heart was real really quickly because I thought I was going to die, it's so scary what your head and the world can do, I'm amazed
Surprisingly I don't get as often as before. Probably I've heavily increased my sleep quality. It often takes me like 15-30 mins to sleep, if I can't I box my cat.
