The only time I remember my dreams is when I am in that "twilight sleep" when it seems like you are half-way in between being awake and asleep. This is when I am also more likely to be verbal (yell) or try to swat (hit) at something,...yeah,...my wife loves this,...not. As far as sleep disturbances go, this is a common thing with autism as the GABA (inhibitory)/Glutamine (excitatory) balance is often off,...usually too much glutamine. Recently, I have been using a cocktail of 200mg L-theonine (glutamine receptor blocker), 800mg Magnesium (smooth muscle relaxer, slows the heart rate), and 5mg Melatonin (sleep aid, antioxidant). Sleep like the dead.
