I doubt anyone reading this has ever tried this, but can dream characters do math? I sure they could do simple things that you have memorized like 2 + 2 = 4, but do you think they could do problems like 13 x 17 or something like that?

That would be incredible if they could, it would really show how powerful the unconscious mind is, but I kind of doubt they can. I think they would probably very confidently give you a random number that is close to what you would think it would be.

Also do you think it is possible for you to do paper and pencil math in dreams? Could your mind actually keep straight what you have 'written' down? Again, I think that would be incredible if it was possible.
