You’re talking about inducing a WILD by use of the technique you mentioned, right? If you’re not I guess your technique isn’t gonna work, because pressing a button a few times before going to sleep isn’t going to do much good, or it could work because in your dream you push a button again, it could make you realize you’re dreaming. If you are, getting into a WILD while having to push a button might cause people to stress, because they know not pushing the button will wake them up. It’s hard to relax that way. And to induce a WILD you have to lay completely still.
