Only ONE dream ????
This may sound a bit bizarre, but hardly a night goes by where I don't wake at some point with a dream that involved tickling, and this has been going on for at least 30 years.  Not that I'm complaining, but I think it goes to show how deep this compulsion can really go.  
Now having said that, I hope there are at least a few among us that can concur with me.  I wouldn’t want to start having that “I’m the only one in the world” feeling again … I’m getting too old for that stuff.
