Do you usually go back to sleep after you have experienced this?
In that case you should be very excited, because it's highly possible that these weird events are actually False Awakenings.
You can use them to your advantage by preparing for the next time it happens, and tell yourself that you are going to perform a bunch of reality checks that time.

Personally I think False Awakenings are awesome, because for some reason I have a much easier time becoming lucid in those kinds of dreams.
It's usually a scenario like "hm, I feel weird, probably one of those False Awakenings again, now let me perform a reality check here --- yep, I'm dreaming".
