I think I hallucinated yesterday

Okay, so I think I hallucinated yesterday.

For some reason I looked at my left hand palm side up, and I saw a bunch of fine scratches. Nothing new about finding scratches, I do that to myself all the time and don't remember when, but then, a couple of hours later I looked again . . .

No scratches. No signs there had ever been scratches there.

I don't quite know what to make of this, folks . . .
