I pushed myself a bit too far over the weekend and an old 'symptom' came back to remind me. Not sure why I am posting this, perhaps because anywhere else I would sound crazy. I start to feel really exhausted within my dream, vividly physical and mental tiredness. This time it was as though I became somewhat conscious and thought something like "I remember this feeling. I must be asleep, dreaming." Then I heard faint voices and remembered my mum told me someone was coming round in the morning and I recognised this as another sign I was asleep, but still couldn't wake up. Overcome, I tried to go to sleep in the dream. Upon this "double sleep" I always get a very uncomfortable sensation in my brain until I shortly wake up to reality with the same feeling. The brain sensation is a bit like a less-electric brain zap from antidepressant withdrawal. Sometimes if I get a similar feeling before I sleep I know I will stop breathing and, though conscious of it, be unable to wake myself until my body suffocates enough to wake and gasp for air. In case you are wondering my doctors diagnosis for this was 'panic attacks'. The bit I find fascinating is that it is the "double sleep" precedes the brain sensation, at least in my perception.
