As you know, really old computers used to “dream” by going to an idle loop which in assembly language was written somewhat like this:
JUMP *

The instruction means “jump back to this instruction again.”

A computer in such an idle loop is constantly doing something, but that “something” is simply jumping back and re-executing the same JUMP instruction. The operating system “wakes up” the computer by interrupting it and sending it off to perform some (other) necessary task. It would seem to me that a computer in such an idle loop is executing the ultimate Buddhist “nothingness” meditation – thinking of nothing at all. But, this type of meditation, although it calms the mind, which is a good first step, is not sufficient to lead to enlightenment.

Nowadays we of course have our computer run SETI@Home or some other distributed computing task instead of sitting in an idle loop. Much better use of its spare cycles! So the answer is probably that my android (my computer) is dreaming of finding intelligent life in the universe. And that’s a pretty good dream as far as I’m concerned!
