im a virgin, and ive had lucid sex before and it feels REAL. The mind is a powerful tool, it can simulate things with good accuracy.

Also as humans we can only see ahead of us, but in a Lucid Dream you can see 360 degrees around you, if your experienced.

Flying feels real too, ive been on a lot of roller coasters in my life, and you know that feeling you get when you go down a roller coaster around your stomach. I get that feeling when i fly/fall in my lucid dreams
