The noise in my head actually gave way to some short (bout 3 1/2 hours) of superior sleep with very vivd and "normal" dreams.
Normal as in I wasn't being chased, shot at, silently screaming, running from 'them', or anything like that.
I was walking on the beach with the salt air in my lungs and the sand between my toes and someone holding my hand...not one clue who that someone was...been having that dream for over 20 years.
