I heard that if you have a large glass of water near your bed, and you put a little bit of salt on your tongue before going to bed, you will have a dream about drinking water at which point you will become lucid.
2 part question
The glass of water near you bed does what?? Is it for later when you wake up and you are thirsty because of the salt
Maybe it’s supposed to induce FA, where you start searching for water because of the salt. By putting the water near your bed, the SC might remember that it’s near your bed, so when you go to drink it, you’ll do RC.
