Yea, I’ve had RCs fail. A lot of times in a regular dream I’ll move thing or unlock doors just by thinking about doing it. It just seems normal in most dreams to have strange abilities. If I get the thought again to try different RCs I think I’m going to try and associate levitating off the ground a few inches with the fact that it’s a dream. First establish in your mind that the two are related. Floating in the air and dreaming. The reason I say establish that in your mind first is because I do it a lot in a regular dream and don’t give it a second thought. Critical thinking.
