Thread: Would this be classed as a dream sign?

Hey, im new to this, i dont think i've had a lucid dream, apart from maybe once a few years ago, but it was only about 4 seconds long and all i said was 'huh, so this is a dream?' then woke up.

But the dream was quite weird, i was at school and was an agent of some kind smuggling some sort of secret package out of a schoolroom and all of a sudden an alarm went off. then i said to myself 'wait a minute, i recognise that alarm' and from the alarm a realised i was in a dream. and i have no idea why, i'd never heard the alarm before in my life, well i think once in another dream, but it just seemed to trigger something in my mind that made me know it was a dream. I'm pretty sure i woke up naturally too, i can't remember if i had an alarm clock but i don't think so, it was a different sound anyway, but its just odd. and since then i've never heard the alarm in any of my dreams nor had a lucid dream i can recall.

And if anyone cares, the alarm sort of sounded like the noise a police car makes, but it sounded like two, one at a faster tempo than the other, i know it probably doesn't make sense :p
