I always assumed everyone dreamt every single night, and that it was just a matter of whether you remember those dreams or not. But maybe that's just me, since I'm a very light sleeper.. I've always had dreams every night and was able to recall every one of them to some degree, depending on how memorable they were. Recently, I've been having extremely vivid dreams of me and accompanying friends flying through beautiful landscapes. They are so vivid they sometimes seem more real than real life. I don't know if it's more a result of daily meditation or painting with Iodine but I've been able to go into these extremely bright and crystal clear lucid dreaming every other night/early morning.
