i can sympathize with your situation...
i have a similar thing going on...
the noise i hear while laying down to sleep is much like a train station, airport, or mall food court.... just a lot of senseless noise that sounds like lots of people talking, etc... sometimes i can focus in on certain converstaions the people are having. its kind of annoying and certainly interferes with sleep.
and sometimes i wake up in the middle of the night cuz i am certain i heard an intruder coming into my house... i even grab a knife and wander around the house like an agent searching for the intruder....

i dont take any meds for it, but i try my hardest to convince myself that these things are just in my mind...
and eventually i fall asleep.
