Is lucid dream a real thing?

It definitely is. While it has been practiced for 1000s of years, it was only scientifically confirmed in the late 1970’s. Lucid dreaming isn’t astral projection or spiritual fu-fu, it is as you say a "real thing”. It’s something anyone who can dream (which is almost everyone) can do.
