I do this too, and I really enjoy it. I have everyone close to me trained to not talk to me when I zone out like that because I find it so pleasurable and relaxing.

Usually I am staring at something inadament, but there are probably times that I inadvertantly stare at a person or situation.

I'm not sure if this is normal, or at least MS-normal, but I have never worried about it as a medical problem. Perhaps I should though.
