Hey guys I have question what is difference between astral projection and lucid dreams ?

Lucid dream is simply a dream where you know that you're dreaming. And you may have some sort of dream controlling ability. On the other hand, it is believed that in Astral Projection or Astral Travel, your astral body/soul could separate from the body and travel physical world a well as astral world or different realms. But we don't have any solid proof if AP is real.
