I skimmed through the read and yes those are really some interesting experiences and being able to see things requires breaking certain limitations and accumulation of quite a bit of energy. For most who try to open their third eye too fast will see the non physical that they are not ready for. I would suggest pychic shielding if you know how because there will be some entities are attracted to it now that you have awareness to them. Not everything you see is positive or negative. But that shadow person certainly was a negative being. Hope you stay safe and protected.
