On completing a task while exhausted

I woke up at my desk in the middle of the night last night.

I'd spend pretty much the entire day working on a paper for a class and managed to pass out without my head falling onto the keyboard.

When I woke up I stumbled my way to bed (all six feet) and pat my pockets down to empty them on the nightstand.

Keys.

Wallet.

Phone.

I then felt a small lump in the breast pocket of my shirt. Without really opening my eyes, I slid my fingertips up my shoulder, looking for the lip of the pocket.

But I couldn't feel it.

I moved my hand up and down a couple of times, puzzled as to why this shirt's pocket was being so impossible to detect.

Finally I opened my eyes and actually looked.

My shirt didn't have a breast pocket.

Also the lump was my nipple.
