I read this method in Leslie M. LeCron's book. It's really easy and you dont have to sleep, dream or being hypnotized. Just get a pen and a paper sit somewhere comfortable and relax a little bit. If you feel relaxed command your subconscious to write.

There is some basic thing what is should be kept in mind, like dont think any words, or think on the method of writing either dont move your hand yourself (), etc. It's okay to repeat the command but if dont happen anything your subconscious most likely dosent understand the command.

If you ask him simple to write, first he draw only lines second... i dont know. I tryed this only today but i think with some practice he can write correct words, spontaneously or draw well. After all if you ask him he will answer with yes or no.

Okay this method dosen't really related to dreams but its easy and funny, leastwise for me.

Have a good luck and sorry for bad spelling and simillar things.
