Every night before I sleep, actually when I start falling asleep, my chest starts hurting so bad and my breathing gets heavy, I feel so confused and I even feel that I forgot how to breathe, sometimes I get scared and find myself inhaling strongly and sitting up, and sometimes I just feel myself panicking, it has become a typical part of my day, everyday I have to go through it to fall asleep, it doesn’t happen when I m very tired though, anyone having the same thing? Any advice? 
I also sometimes see confusing lights, or scary images, like my chair turning into a scene from a horror movie, 
And I have a lot of dejavus during the day.
If anyone can help me, please don’t hesitate, anything
