Split, Part 2

I leap from bed in the middle of night
Run up the stairs for 3 or 4 flights
Run in a room, turn on the light
The dark is too dark but the light's too bright

Reality is hard to find
Like finding the moon if I was blind
It's there so stark, so undefined
I must get help before I lose my mind

I try to think of things mundane
To get this terror from out my brain
Everything's so mad, I can't explain
I must get help before I go insane
