Crazy?

So I'm sitting there today, in my room, just trying to calm my mind down a little. I turned off all the lights and any sound-producing device, got comfortable, and started letting my mind wander. I try counting down from 10 to zero over and over, which usually does a good job removing my attention from reality without knocking me out, and I start having a conversation with some people. Mind you, all these people are made up, but I'm half dreaming so it's excusable. I think. Anyway, I'm having a little argument with some guy and he uses the fact that he did something (what, I can't remember) on his birthday. My response was "you're lying, you never had a birthday. You don't really exist." He disappears, and I continue the conversation with everybody else. I eventually drifted into unconsciousness, and woke up groggy as all hell.

Weird.
