Dream reality/Astral projection/Inter

Sounds like a stretch, but I've heard more and more people talking about their experience with shifting into a new reality. If any of you have done this and it really exists, or if you want to share tips, stories, etc. please tell me how I can escape this reality for a little bit. It sounds super interesting and exciting, and I don't want to sound gullible, but this is something I could get behind.
Best,
Lilly
