I once read about a young man who claimed to have had some sort of head injury when he was an adolescent and as a result slept a lot longer than most people do.
He said he got to the point where his waking life — which consisted of waking up, going to the toilet, having something to eat and going back to bed — felt more like a dream than his dreams did.
He claimed that in his dreams he had a wife, a job, the perfect little world and the perfect little life.
He also claimed he had lucidity but that he kept things as normal and mundane as possible; electing to forego flying and summoning weird and wonderful creatures and what not.

While I realise this isn't exactly the same as being addicted. I couldn't help but feel pity for this guy. I imagine if you were addicted, this is what you'd be like and you'd have my pity.
