Hi, i'm wondering if anyone else has ever had this symptom, and if there are any suggestions at to its cause. Just to say to begin that this only happens when my M.E is worse or if i'm in a bad crash. I had it a lot a few years ago and it has now reared its head again alongside a general worsening in my health. This is what happens - some nights i wake frequently and when i wake up i am very very confused. I am not able to work out where i am or even who i am or even what i am or what i am seeing. It doesnt last long - usually long enough to scare the hell out of me, and then gradually it becomes clear. I am me, i am at home etc etc. I have had a version of this for years which i think is relatively normal where i wake up and can't remember what house i am in or what age i am - but this is much worse and really horrible. Last night i remember looking around the room from my bed, not knowing who i was and then suddenly i had an inkling about it all and i said out loud 'are we at home?' i had been trying to work it out for a while but the answer wouldnt come. Once my husband said yes we are at home, it all fell into place and i felt ok again. It really is very scary and i hope it stops soon. Justy.
