I've tried the computer thing before. In my first lucid dream I made one for my mom (long story) and it was a black DOS screen with the old MS slogan 'Where Do You Want To Go Today?' at the top and a blank command prompt. I wasn't very lucid so I ignored it and went to do something else. I think i'm going to try that and the phone thing next time I'm lucid. Is it absolutly vital that the numbers are correct because even in lucid dreams text and numbers tend to be a little hazy and confused for me :?
