They're always watching...waiting...

Now close your eyes under the shower, while stoned. Now that's a trip.

For me, it's when I'm leaving a dark isolated area and going to a more "safer" place. Like I'll be fine out in my dark ass yard, but as soon as I turn to walk inside, I imagine a hand reaching out to grab my leg, or some creep just staring from the tree line. I walk a little bit faster.
