This looks good on the whole. I have only two comments at present: first, you should specifically call out that being damaged in a lucid dream has consequences for restful sleep (i.e., you lose an hour of sleep, for spellcasters, or something of that nature), and there should be a larger penalty for being "killed" in a lucid dream.

Secondly, the synergy with Forgery is odd; I would expect Bluff to work better, since you're not writing anything down.
