What the old hag is looking for

Amanojaku's comment : this dream is one of japanese urban legend and it said to be dreamt by children
In the dream you are standing inside a room. And there you see an old hag who is frantically looking for something, rummaging through drawer after drawer.

You ask her, "what are you looking for?"
The old hag turns around and spreads out her hand.
"I am looking for my little finger."
You look at it and sure enough her little finger is missing.
Then the old hag asks you, "can you help me find it?"

If you have the above dream, make sure you say yes to her request, and find her little finger.
Because if you can't find her little finger, you will never be able to wake up again.
