Why did i wake up?

I was running around town at night, it was dark. I half knew I was dreaming, and when i got to a bridge in the middle of town, I fully knew I was dreaming. So i was like, well why not speed up this trip? I jumped up really high, I think I went through the clouds! The I fell a bit and I wanted to fly, because I've never done it before. So I made a stuck my arm out like Superman and started flying! It was extremely easy! Bit I started to see some square form, the border first and quickly closing in. It was my ceiling. No!!

Why did I wake up? I wasn't pumping with excitement from flying, I just started to wake up out of nowhere. I think I might of had my eyes open to wide and when I woke up they were open wide. Any ideas why this happened?

Even if something isn't exciting it can still wake you up, flying can be very unstable for people, well done in achieving it though!
I recommend attempting a DEILD when this happens.

^ Arch is right, try out a DEILD, they're so much easier to do when your lucid as well.

When you figured out you were lucid did you try any stabilisation techniques? its always better to ground yourself in the dream before you start flying off. Congrats btw... I can never get that high, i might have to try a big jump too :P

Good luck.

Yeah, I never really stabilize I always forget lol. And do you think it could've been a FA? I never wake up with my eyes wide open. And I was barely thinking when I jumped, I just did and went super high :P I'm always dumb in my LD's and either forget them or wake up early.

It could of been a FA.... They're sneaky little sh**s :P

Always gotta do a quick RC to try to catch them out.
