"Waking Up" Within My Lucid Dream. Caught In A Loop.

Hi guys. I just registered here and I would like an explanation to whatever I just experienced in this lucid dream.

So a couple of hours ago, I got home from college, and after a few hours, I was very tired so I decided to take a nap. So I did, I took my nap.

In my nap, I had a lucid dream. In the dream, I woke up (I read about this "waking up within a dream" but I don't remember what this is called), and immediately started living my life. I noticed some things were changed so it was definitively a dream. After that, the same thing happened (hence why I said caught in a loop - this happened a few times), more things were changed and so it was a dream, and so I woke up again, and more things were changed. I started to desperate because I wanted to wake up in real life, but I couldn't. I started to do all kind of things with no luck: Jumping into a cool pool, hurting myself, and in the "cycle" before the last one, I actually attempted to commit suicide and jumped from a building to see if that would wake up me. Boy was a I wrong, because another annoying cycle started with weird things, and I was starting to cry in the dream. Luckily for me, my cellphone rang and woke me up.

In the last cycles of the dream, I started to see the time and it was late (something weird because I don't have to go anywhere or do anything today, but the clocks kept showing 4:00 and 5:00 PM). I think I saw that because I hate to spend too much sleeping in the afternoon, though.

Any enlightenment will be highly appreciated.

Those were FA's (False Awakening). Basically your mind tricks you into believing you woke up for real. FA is a good way to become lucid if you can catch it. Everytime you wake up, perform a reality check, and you will know you are dreaming. Sounded like you had a long run of lucidity, you could have had some fun instead of trying to get out, but I can understand you if you were scared etc.

I also had a dream where I felt I was stuck and the only way was to commit suicide. I was on a building too(rooftop) and jumped off the edge but flew around instead(I was semi-lucid).

This is a treasure trove of lucidity, if you had known what was happening. Performing Reality Checks when you wake up is an excellent way to combat False Awakenings like you experienced. Next time, after you realize you are dreaming, instead of trying to get out (its impossible to be trapped in a dream indefinitely, not inception lol) have some fun.

I've had the exact same experience. It is quite disconcerting... My dream guide helped pull me out of it, if I remember right. But reality checks after waking really help. But it seems you already knew it was a dream for the most part... Past that, I'm not really sure what to tell you. I've had the experience once only, and it scared the hell out of me. I did notice that I could tell a FA because I actually got out of bed when I woke up, though. Didn't help me too much, being lucid.

I haven't experienced false awakenings before, but an easy way to combat them, like others have said, would be to perform a reality check the instant you 'wake up', every single time. Good luck. :)

EDIT: I'd recomend doing the nose pinch reality check. You can do that without getting out of bed, you only need to move your one arm.
