Hi, welcome to DV!!

Well, sounds like you are almost a natural, being as you've had four or five lucid dreams already...I would definitely check out the tutorial section and look up some of the induction techniques...you might do well with the WILD technique, having already experienced sleep paralysis and been conscious of it...

I had a similar experience to you the other day with a dream character, trying to get them to tell someone else in the dream that this was a dream, but he wouldn't do it...
I guess you got lucky!
