It's a struggle to stay present and in 'reality' so to say, as the dreamworld is such an intensively grand and mesmerizing place.
I wouldn't want to be without it, though. It's escapism at its finest. (Ha, my achille's heel!)
When I channeled my creative ticks into writing, I improved massively as a Scribe... It's a huge time-sink, though.
So yes, as Wolfheart stated - it's common for people on the spectrum have their own sanctuary, so to say.
