Is there any research about the correlation between sleeping postion & which part of the bed you take?

 

Just realized that for such a long time, I only slept on the right part of bed, facing to the central.  I like lying on the left side, since this is the most comfortable postion to hold something, like the dog or the neck. Is it some kind of implicit expectation of warm & secure feeling?

 

Life cannot be always like this. Unbalance would destroy a lot of things. I took the central space for the first time.

 

Nightmares are gone.
