This is the last of 4 dreams I had last night, but I only remember 2 of them. I've recently had surgery on my right hand in real life.

I'm in a house, walking around, and I suddenly look at my right hand, and it looks really weird. I examine it and realise that I have no thumb on my right hand. I decide to count my fingers, and I have five fingers, but no thumb.

Someone else is in the house, but I don't remember who it is. I start calling out to them, saying that my hand is really weird. This causes me to wake up.
