Sides of the head

Hi, sometimes I will wake up in the middle of a dream and try to go back to sleep and continue the dream. Now if I rest my head on the pillow lets say on my right cheek and I was sleeping on my left cheek before I woke up, I have to turn again because it is imposible to find my dream again on the "wrong cheek side". Does that make any sense and why is this?

Any reasonable scientific explanation to this?

thank you all

Sounds to me like it's happened once and you started believing in it and now you can't change that.

I absolutely can't sleep on my right side. If I roll to my left, I am asleep in 35 seconds. There is a correlation between which side you are lying on, and brain activity. I remember everyone participating in that Lucidity Institute study before they switched over to internet silence.
