It's eerie, awesome, and terrifying all depending on the dream.
A few nights ago, I dreamed I spotted a guy with a sniper laser pointing it at a guy in a window in a neighboring building, so I somehow magically forced myself to teleport to the sniper's location, and it turned out it was his eye itself that was the laser, so i ripped the laser out of his eye and a long electrical cord came out of his head, so i pulled it out, tossed him off the top of the building, and then I woke up like, "WTF, I just killed a cyborg sniper assassin". Not a bad way to start your day. OR, a terrible way to start your day. Depends on how you look at it. Either way, I was in semi-control of the dream the whole time.
