Dreams merging with reality?

I had a succubus melt and become a curtain once when I woke up... so I understand. So long as you are keeping the difference between reality and imagination separated while you are awake... it's no big deal. You might try keeping a journal and see if you are eating/drinking or doing anything in common before these dreams... if so you might be setting them off yourself.. and might be able to control them with simple lifestyle changes.
