I have been keeping a dream journal for the past month, from the 5th of April to last night, the 30th-1st May. Every night has had at least one dream, save two nights, which just didn't have any. Most nights have at least 3 dreams, sometimes 5.

I'm not sure what technique I use, but this is what I do each night:

I go to bed around 11, sometimes 10. I usually stay awake past 12, maybe even to 1 in the morning. I always just lay there, relaxing my body, not moving at all. Ignoring itches, twitches, and the urge to turn over.
I achieved S.P. (Intense tingling in my entire body, a rushing sound in my ears, lasts maybe 4-5 seconds) 3 times so far, 2 in one night, and the other a few nights ago, all after going to sleep for a few hours, without dreaming.

....but thats it. Nothing happens afterwards. I get S.P., which is the furthest I have gotten, and then I just can't get it again, nor fall asleep. I eventually do, but without knowing it, and then I dream. When I dream, its either watching over an event without a body, or I don't think of doing an R.C.

I don't do R.C.s in real life, as I tried it for a week once, but nothing came of it at all.

My question: What should I do next? What should I change, start doing?

Thanks for reading it all, hope it wasn't a wall of text for you!
