How to have lucid dreams?
it takes a bit of effort/research and dedication
there are multiple methods, your basic ones such as WILD (Wake induced lucid dream - basically relaxing your body and letting your body fall asleep while keeping your mind awake) and MILD (Mantra Induced Lucid Dream - Doing Reality checks during the day to remind yourself if you're dreaming or not and repeat a mantra in your head before falling asleep and hope that you realize you're dreaming based off your mantra/RCs) and more advanced ones such as FILD (Finger induced lucid dream)
really it's hard to explain all this at once so go to DreamViews and just research a little bit and start to get into it. to be successfull at lucid dreaming you really have to get into it.
on the plus side remember the reward of being in a world that feels exactly like real life, at times even more intense in feeling and senses and being able to do whatever you want and experience what you want (inb4 loving every hot girl)
