I feel your frustration but keep in mind that the supplements aren’t a guarantee to lucid dream. for me LDing became an obsession before I had my first one. I stayed on this forum as much as I could to learn terminology, experiences, questions etc. shout out to all the people who helped me on this forum, I think if it wasn’t for the experienced ones taking time to answer my questions, I wouldn’t have gotten this far! I also read books on lucidity. Get a dream journal to record what you saw/felt/heard etc. even when I didn’t have dream recall I would still write in my journal, “no dream recall”. I’ve learned that being lucid requires discipline and brain re-wiring.
The technique that I’ve had 98% success with is WBTB and WILD. I have atleast 5 LD a week and im a newbie! Im a 100% sure that WBTB will at least give you a vivid dream, if not a lucid one. I sleep for 4-5hours, wake up, focus my thoughts on lucidity and then try to fall back to sleep. 4 out of 5 times I wake up to a false awakening in my bed. I do a reality check, once I know Im dreaming I get out of bed. Take some time to learn techniques and play with them, it took me a week to figure out how much sleep I needed before I woke up.
I read that WILD is one of the more advanced techniques but as a newbie, that’s the only one that seems easiest for me. basically, TRY as many techniques as possible to see which one works for you. I also mediate any chance I get for about 15-20 minutes just to become familiar with that state of mind. you’ll have one soon. youre on the right track!
Good luck and sweet dreams.
