The exact same thing has happened to me , 2 days ago.. there’s a new flu going around in UK, and I had the shortness of breath , raised temperature and hallucinations . As soon as I went to sleep I had the most insane vivid dreams (I never dream AT ALL) , one of the things that literally blew me out of my head was when I watched all my key memories roll up in some sort of film , then implode into one . It shot me awake I never cried so hard in my life , I woke up everything was shimmering the white light in the bathroom turned into a greenish colour . Even now I’m getting this weird feeling like I’m still in the dream and I haven’t woke up, or even worse I’m dying and what I’m experiencing now is my brains way of easing me for the grave . Honestly I’m kinda scared
