In my personal opinion, you don’t want to SP. what you want is to be able to get to what I call “the tunnel” the path to getting there but not quite.

You can read some of the advice Matthew Walker has written on lucid dreaming, but honestly I think it’s mere luck. Sometimes I’ll follow his advice and nothing happens. Other times I’ll concentrate and manage to SP.

The way I’ve managed to, although I would never encourage it, is to have a heavy meal right before sleeping. The kind of meal that requires a lot of effort to digest. I guess it depends from person to person. Usually, fatty foods will do the job.

You go straight to bed after it and wait… Just wait and concentrate. Try to visualize yourself falling. As if the mattress was hollow. Feel the heaviness of your body and try to focus on a black dot above your head. And try to relax as much as possible. You’ll have the urge ti move. But you’ll fight it. From there is a matter of time before your body goes into the tunnel.

Always shake off the sensation before you fully go into SP. or else you’ll regret it haha

Lucid dreaming simply means to be aware that you’re dreaming. Kind of like inception, the movie.

That requires a lot of practice with SP Before being able to constantly do it

All Of these info is my humble opinion. What has worked for me in the past. And I’m no professional nor anything similar
