You mean moving objects that are in the dream?
Or do you mean moving objects that are in this reality, from the dream (perhaps not exactly a dream but astral / out-of-body experience)?
I have had some success with both.
For telekinesis on objects within a lucid dream, I guess it depends on the plane that you're on. For most of the time it's very easy to fly objects around, levitate, teleport, etc (astral on higher-frequency planes, I think). Sometimes it takes a lot of focus and willpower (more than it would in this reality) for it to have any effect (astral on lower-frequency planes, I think). For me it usually feels like being one with the object and moving around.
For telekinesis on objects in this reality, from dream / astral / OBE, it seems a focused intention is necessary just before going to sleep. It feels the same as telekinesis on objects within a lucid dream. However, for me vision or sight is usually different. It's as if only the target object and its immediate surroundings exist, or I'm attuned to a spatial area. The rest of it is sometimes just very blurry, sometimes the rest of it is just plain white, sometimes plain black or dark violet. The target object and its surroundings are like an island of clarity in the mist or so.
Also, I've noticed that psychokinesis on objects in this reality seems easier while I'm in a half-sleep state (the body is about to fall asleep). A single thought or visualization may cause stuff to happen. For example, there's a lot of noise coming from the other room .. can't sleep. Bang, the door flies shut. Or someone left the TV on and it's annoying .. electrical blackout. Though, geisting is more serious also.
