So this is the first time this is happened I think so should I get a new reality check?

Basically I was in a dream and this meteor hit the earth, then I was like to everybody in the dream a meteor just hit and they didn't seem to care much so I was like hmmm lucid dream perhaps so I pinched my nose and tried to breath...but I couldn't. This reality check usually works perfectly but for some reason it didn't this time! Or perhaps this was a premonition and not a dream, nahhh that's looking to deep into it.

Your thoughts?
