Total noob here but isn't lucid dreaming a better and safer way to explore dreams? Why not learn to control ur dreams instead of inviting something in that u might not be able to control?

With lucid dreaming, I've managed to turn these nightmares around. Once I realize I'm dreaming, I confront the chaser, decide not to fall, or just smile in a mirror when my teeth start falling out. It takes practice but it helps you understand your fears and anxieties better.
