Unwelcomed Friend

I sit and wait inside your thoughts Looking for the most opportunistic time Then after I simmer awhile I make my move And boom I steal your mind I watch and wait like a stalker does I learn your every move Than I invade you most private thoughts Ones not meant to be known I leave a mess wherever I go Just so you know I'm there I really do get my rocks off Watching you as your scared Making sure not to leave my prints My identity never known I just want to know I was there You're never ever alone I laugh at you from the inside As you see all my nasty tricks I'm clapping so hard my hands they hurt As your taken away by ambulance I'm that fatal dose that takes control My pranks have all been played And though I am a figment of your imagination Paranoia is my name
