Just as you go to your closet to choose different clothes, to emphasize different aspects of you. The human soul essence can easily transform its form in the fourth dimension by changing holograms or shifting their DNA with their thoughts. But when your thoughts and sensations are dark and mean spirited, it’s like having all black clothes in your closet. Your 4D form will usually be a scary form created with your fear. If you want to channel your inner fairy, you think and feel like one.
Time in 4D moves faster because there is no biology / physicality to maintain. A few minutes of third dimensional time can be an entire lifetime in the fourth dimension. When you have split off aspects of YOUR personality you dislike or disapprove of, they become a separate entity that is generally scary, ugly and not very nice because you rejected them. YOU terrify you. Your nightmares are of you being trapped in your own fears about you.
Shape shifters are considered myths within the third dimension reality, but are common and real within the fourth dimension. The highest sub plane of the fourth dimension has Mystery Schools for spiritual training that can be visited in your dreams, meditations and higher brainwave states.
