I can only remember bits when I wake up but once I fell asleep on the couch and felt myself wake up,sitting in the chair was my dad who passed away in 2002 and he was smiling then I felt myself wake up again.Even though I must have been sleeping the first time I "awoke" I realise I must have dreamt that I was awake but it seemed so real because I actually woke up with a shock twice.It was a bit of a buzz really with all the adrenaline going through my body.
