I finally got my 2nd lucid dream yesterday, far more extensive than the dark room and cut-off 1st one!

I was at my school. I don't remember what really happens. But then, I arrive at a school, but I realise too late it was the wrong one. But then, I was like:
"Wait... that's not possible in life. I must be dreaming!" I then set off to do the reality check as I did before, but it wouldn't work. However, at a moment, the 'teacher' said: "Oh my gosh! His finger went through his hand!" I set off to attempt things, but to no avail. I returned home, and I tried flying through the window, but I just ended up smashing my face in it. I tried many other lucid things, but they just would not work for me! However, time seemed to change when I hid my digital clock and showed it again. I tried something at school, and it involved seeing if I could get my hand through someone. I think that thing worked. But the dream ended a while after.
However, I don't like how I was limited to my dream control. I mean, I couldn't go through the window, even though I imagined it to be pass-through, and when I tried to fly, I only glided down the stairs and through the hallway, and stopped. D:

Any suggestions to make my next LD better, and while we're at it, suggestions to make lucids more frequent?
