I was about 8 the first time I was aware I was dreaming. It's not really noteworthy, except for the response from the characters in my dream.

We were all lining up to go in after morning recess. I was in line when I realized I never woke up. I went from being in my bed to suddenly lining up to go to class. So I screamed "It's a dream do whatever you want"

The entire school started running around like they were nuts, and the teacher finally calmed us down. I was crying and said "I thought I was dreaming". The teacher told me "How would you like it if someone did that in your dream"

Sadly, this was back in the late 80's, and didnt have internet access. My next experience with a lucid dream wouldnt happen until around 2001.
