This isn't a dream for me. Mentally I'm awake I can think, feel my body the sheets on me and all; I can't move or breath. It starts out as abnormal dream then I struggle breath which quickly moves on to my brain being awake and my body isn't. Every part breath is a fight (I can take tiny gulps of air and it's difficult) moving my body a certain degree instantly wakes me up, when I wake in breathing heavily and my heart is racing. Trying to move is a challenge as well, I can move certain parts of my, my neck and legs, a tiny amount and I can't push them to far as I cannot muster the energy to do so. Eventually as my lungs are getting tighter and just snap my neck left or right and I shoot up in my bed.
It's concerning cause it's come back after a long and it seems like if I don't try to fight it I could pass out
