Paranoia

Dunno why, but i've just been hit by a sudden wave of paranoia. I may be in bed with the lights out, but faint noises coming from outside my bedroom made me go out and check the house from hall down to the kitchen. Am back in bed again under the blanket. I even heard my mil walking out of her bedroom, turning the bathroom light on and peeing into the toilet bowl. Ok. Had better catch my few precious hours of sleep.
