(do it tonight!)
So the best time to astral project a lot of people think: «Right when you go to bed is the best time to astral project». And I have done this, many many many countless times. But for me personally the best time is when you're about to take a nap. I usually take like an hour, an hour 30 minute, naps. Since they're a little longer, I'm able to astral project, and actually have more time to get into the mindset for this.
