I see artificial telepathy has turned out well.

My most recent dream had me hanging out with an old BF at school. We were studying for a test when we got up to hear the announcements which were all mumbled because the speakers were broken. I whacked it with a broom to get the dust out and a car key fell out. I was curious, so we went to the parking lot to use it to see what vehicle it belonged to. We then went to the vehicle that lit up only to learn it was a time machine, so we used it to go back in time to what the time machine said were "previous dreams" to change the "dreamtime continuum". The dream ended as I ran up to twelve-year-old me and yelled "don't go down that slide onto the noodle, you'll die" and past me said "hey look, you're fading".
