My dad who is also into things like meditation and lucid dreaming told me that the position you sleep in does affect your dreams and sleep quality. Not the actual position but the direction your head is facing (North, East ,West, South). I think he said head facing north gives the best sleep quality.

So it would be interesting to see if its true and weather it affects dreams or lucid dreams and sleep quality overall. So maybe people would be interested in testing it.

Need a few people that can change their position in all 4 directions. The experiment should take a mounth, a week for each direction. The people who want to try this need to have good dream recall and they need to have a journal for the test month. Need to write down every all the dreams during the month and eventually compare them with every direction and with other people dreams.

If some serious people are willing to try this we might just discover the best sleeping position.
