Making Progress?

So last night I was covered by an avalanche while zombies were out to get me. Luckily I knew there was a polar bear moving the snow around to find me. During this I actually thought to myself, "Hmm I must be dreaming." I woke up right after this (Not sure why). I don't think I became lucid exactly, but maybe I would have if had more time in the dream. This is the first time this has happened! So I'm making progress yes?!? I've been keeping a dream journal for about three weeks now and I think I'm getting better with recall. So many completely illogical things happen in my dreams I really hope this the start of catching on to it. Any advice?

If you think that you are dreaming while you're dreaming, then that means you were lucid. (for a split second)
What woke you up was most likely the excitement.

Yeah, if you want to prevent from waking up because of excitement, all I can say is: practice is the key.

hmm thanks guys!

Yup, you were lucid. Mark that wherever you want to keep track.

A classic first lucid.
