Hello instructors! My question is regarding astral travel. I'm just a beginner at this so I have a lot yet to learn. Sometimes when I leave my body I'm able to go through the bedroom walls and ceiling. Quite often I end up in another room which is not part of my dwelling and upon trying to go through those walls to go outside I'm much denser and unable to go all the way through or not at all. Is this something my mind has manifested or is it because I'm just a lower level of consciousness? Is there anything I can do to help me with this process?
