To start off: I have never had a lucid dream. I am quite knew to the idea of lucid dreaming and had a question.

A friend fo mine who read several books on lucid dreaming said that one technique used to "trigger" you mind into knowing you are dreaming is to try and read in your sleep. Appearently text in dreams is never the same twice. So if you looked at a stop sign it might say STOP the first time and if you looked at it again it would say TOSP or something like that.

So, he said that while you are awake everytime you read something you should look away and then look back and reread it. This will train you that everytime you read something you will automatically reread it. When you are asleep you will read something look back and see it has changed... then you know you are dreaming and can have a lucid dream.

Is this a true and documented fact that text changes in your dreams?? I wonder why if it is true.
