The mistake almost everyone makes during their first shamanic journey...
They try to force visuals. They think if they aren't seeing full HD cinematic movies in their mind's eye, "nothing is happening."
Shamanic journeying and Reiki work through somatic sensation, emotional shifts, and intuitive hits way before they ever show up as clear visual images.
When you journey or do energy work, what is your dominant sense? (Clairsentience/feeling, clairaudience/hearing, or clairvoyance/seeing?)
