Geto Boys - My Minds Playing Tricks on Me

 At night I can't sleep, I toss and turn
Candle sticks in the dark, visions of bodies bein burned
Four walls just starin at a nigga
I'm paranoid, sleepin with my finger on the trigger
My mother's always stressin I ain't livin right
But I ain't going out without a fight
See, everytime my eyes close
I start sweatin, and blood starts comin out my nose
It's somebody watchin the Ak'
But I don't know who it is, so I'm watchin my back
I can see him when I'm deep in the covers
When I awake I don't see the motherfucker
He owns a black hat like I own
A black suit and a cane like my own
Some might say, "Take a chill, B"
But fuck that shit! There's a nigga trying to kill me
I'm poppin in the clip when the wind blows
Every twenty seconds got me peepin out my window
Investigatin the joint for traps
Checkin my telephone for taps
I'm starin at the woman on the corner
It's fucked up when your mind is playin tricks on ya
