Thanks for the reply chance7hope, I know the info is not a lot but as I wrote I couldn't manage to get any more out of him, hope the experts here at dreamviews check this post and leave their thoughts.

I don't really think the plugging is related to SP (directly that is), as I said, he feels this sensation as soon as fifteen minutes after goint to bed. Maybe his sleep cycles are mesed up?

I know everyone is different and all of that but him being a natural and them being so rare I couldn't miss the oportunity to try and get some kind information about how he does what he does. By eye rolling I meant like looking to the ceiling with your eyes clossed.
