hey almasquerade

I seem to be repeating myself a lot lately - lots of people with nightmare problems of late.
What truthbearer said, is the basic idea. You need to learn to make that feeling of something strange, or frightening, or not nice - your 'dream sign' ... and whenever you have one.. you check if its a dream. You can read the reality check list in the tutorials for ideas on how to do that

I think this calls for a tutorial in fact... No offense to you almasquerade, but repeating it over and over is starting to lose its novelty.
So keep watching the tutorials section, I'll whip out a nightmare therapy tutorial soon
