I love that people are discussing things like effects of sleeping on your left vs right. My friends all say I'm an overanalyzer (strong left brain), and thus discussing the subtleties within the content of this thread with my friends does little more than reaffirm my reputation as an overanalyzer. As a data point, I find that many nights I prefer to sleep with my right side down.

For at least 10 years now beginning in my early 20's, I noticed being able to remember my dreams if I relaxed and returned to the position I was sleeping in. I have experimented with this and perfected my skills at this over the years especially when I wanted to get back into a great dream.

I would go further than left vs. right and include face-up and face down. My best shot at remembering my dream comes from returning to the exact same head position I used when sleeping. As I was learning this, a number of mornings I would try to relax and remember a dream for 5 minutes or more with no luck, then after rolling over to my sleep position, scenes from my dream would return to me.

I found this thread because I want to see if I can strategically choose a sleep position to increase my abilities the next day and I think left, right, face up, vs face down matters. To anyone skeptical, I would agree that other things may matter more like amount of sleep, excitement, stress, diet etc...

Based on this thread, it would seem that in order to increase my right brain (creative) abilities and balance out my tendency to be over analytical, I should sleep with my right side up (right nostril unclogged). I'm going to pay attention to this now and see...
