Yes this is TGS or Theta Gamma State as E.A. calls it. Michal Raduga who teaches tools and techniques to astral travel from this state calls it The Phase.
If you browse through the tutorials we have for astral travel and there’s a lot about trances in there, maybe see if any of those ring a bell. I’m going to go ahead and link Michael Raduga’s youtube vids there as well, I can’t remember where I put them, maybe in my journal He has a book out as well called The Phase.
