it is an amazing Richard linklater uh the director it just for the philosophy alone in it it will blow your mind it's exceptional but it's a beautiful tretis on dreaming and lucid dreaming and in that they describe a method where during the waking day you are constantly perhaps you can set an alarm and you're constantly reminded to go over to let's say the wall and flip the light switch on and off on and off on and off and sure enough what happens the lights go on and off why because it's the real world and it complies and it's complicit with the laws of physics so you do this time and time again and you start to train yourself that at unique moments throughout your waking experience you always go over and you test some version of reality and it or it could just be I'm going to press my hand into something solid and this table is resisting my hand right now as I'm pressing and I just keep doing that and then at some point it becomes routine enough that you start to do that same thing when you are dreaming but now when I press my hand against the table or press my hand against the wall my hand goes straight through the wall or I flip the light switch on and off and the lights do nothing and all of a sudden that's my cue to say I'm not awake am I I'm I'm dreaming and therefore at that point I gain Lucidity and it increases the probability
