I had that similar sleep distrbance last night. lay awake for over three hours, possessed by thoughts which increasingly began to manifest themselves in a strange manner etc. loud music.
Eventually caused me to freak the **** out about a particular thought and feel myself screaming inside, and really want to scream.
I sent my screaming thoughts in an sms to sasha but learnt in the morning that it didn't send. Probably a good thing.
