Mysteries of my subconscious

Okay, keep in mind that I am 16. And that lately in order to become aware, in my dreams I would just KNOW that I'm dreaming without a reality check, and sometimes don't even use a reality check. (which I know, is bad.)

So, it started out as me being in school one day. My friend that I kinda avoid hanging out with sometimes asked me to hang out with him, and I kind of avoided it. I rescheduled anyways. Then I went into my classroom that I was supposed to go into. It was my CAD classroom (which is a 3d computer design class). Then my teacher showed us a new seating chart, and I went to sit in my seat. Moments after I got there I appeared in this courtyard at my school that wasn't my actual courtyard.

This is where it starts getting weird...
I was in a dream scene that I had been in previously that night for an entirely different dream. I believe it may have been in a dream of mine last night too.
So i hear people chanting something about dreaming, and then I quietly chant that "I will have a lucid dream tonight" I kept chanting it to myself and I only did a small reality check to ask if I was dreaming. I didn't catch myself one bit.


Later on into that dream, I felt as if I woke up in waking life, and then rolled over in my bed and the scene changed again into a water world that was portrayed as a video game world in my head. I WAS the character in the game though, and I WAS actually scared of the feeling of drowning. At one point, I came into realization that I messed up in my last dream. That I didn't do a reality check. Then I was telling myself I have got to start looking at my hands more and really focusing in on that stuff, no matter what. I didn't do one reality check I believe.
I carried on just thinking that.

And then, I felt as if I kind of woke up. I felt myself roll over in my bed, keeping my eyes closed, and affirming myself that I would become aware. I continually did that. Then I felt some shaking, and I heard another bed shaking inside my house, and I feared something might be happening to my mom, and then I was focusing in on that. I felt my cat lift it's head up and jump off my bed. Then I rolled over, opened my eyes, and was in my room and all the shaking stopped. My door was closed [so a cat couldn't have been in my room].

What was this for me? Was it vibrations and those vibration noises? Because like I said, I felt my cat jump off my bed. Could that have been my dream guide as I was entering into the dream? I didn't feel any sort of sleep paralysis, because and I was able to just roll over twice and open my eyes within those few seconds.
I sort of thought that this sensation was awesome though. I thought it was exhilarating once I woke up. I simply loved it. I thought it was a great dream, even though I only reached layer 0 minor in the layers a lucid dream.
