I've had a very severe sleep disorder for about 18 months, which included severe sleep apnea. I've been on multiple sleep medications and CPAP. I lost many friends on 9-11. I haven't yet been able to figure out if there is any association between certain events in my day and the nights that I have horrific dreams, but I wonder if there is an association. There are nights that I am awakened to flashbacks of the aircraft flying into the World Trade Center, sreams of people jumping/falling from the World Trade Center, and a smell of burning flesh and jet fuel. There are nights that I awaken to other horrific events. I am fried.
