for a few years, ive been trying something. I had the idea of while im in a lucid dream, thinking about something i had forgotten, like the name of a song or anything else, in my case it was where i put my cellphone, then finding the lost information in my dream. It took me a while because i could not remember to think about my cell phone during my dream. But I thought about it last night during a lucid dream, AND I REMEBERED WHERE IT WAS. It seems easy but i found it difficult. Please try this and tell me about it.
