I do a lot of reality checks, probably about one every 15 minutes. I make myself seriously question it every time, but it gets a bit sickening.

Sometimes, when stressed or something, I'll do what I consider too many. Obsessively talking to myself:

"are you dreaming? are you dreaming?"
"no"
"how do you know?"
"because i fucking know"
"but how do you know?"
"because i remember everything that happened. I'm aware, i know how i got here, all of this is real, detailed, i'm cold. i wouldn't be cold if this were a dream. my hands look normal. the clock is the same. okay? happy?"
"but that can happen in a dream, so you don't really know..."

It is literally like a dialog with myself, as happens to me often. But I've been annoying myself with this 'are you dreaming' thing a lot lately. A couple days ago, I was stressed after school, and I swear an exchange similar to what I described above would occur in my head about every 60 seconds. It got so frustrating, it wasn't fun or exciting anymore, just annoying. I think in this case, there can be too many reality checks.
