Your speed is limited to 50 mph, and the amount of time you can fly per day is completely random, from 5 seconds to 12 hours, and you never know until you suddenly start falling to the ground.
You can telekinetically move only one random, oddly specific object, and it's random each day. It could be a tectonic plate. It could be an actual plate in some guy's cabinet. But it will never be a sentient being.
only if the walls are made entirely out of drywall. and you can't just place your hand to see if it falls through, you have to commit to walking through it.
