I used to have the same problem,but then i realised that every night i went to sleep,id leave my "red bulbed" lamp on i i was obviously confusing all the passing drunks and johns that were mistaking my home for the brothel down the street! So my advice to is if you have a red lamp, SWITCH IT OFF!
I was asleep but you know when someone�s talking to you whilst you�re asleep and you slowly start to hear them in your dream. It was like that someone knocked on a door in my dream and I woke up but knew it was my flat door but didn�t hear it after that. Then need a wee but daren�t go in case there was someone outside my bedroom door :-(
