While watching the movie "Insidious," the term Traveler was used,(I don't know if anyone has seen this movie, so I don't want to reveal too much!) The little boy in the movie apparently astral traveled while sleeping and had run into difficulties because of this. I have shared here about some of my dreams that felt real, where I was in other countries and strange houses; my question to all of you is this: Is there such a thing? I am trying to determine if this is just a Hollywood construct, or if this is an actual thing.
