When I did the Fehu experiment, I actually had a real sense of peace, calm, and cool collectedness. I was totally relaxed. I think perhaps if I knew nothing about Fehu I would have been like huh, "I'm staring at a doodle," so I think it helps if you know or have a generalized idea of what the runes mean, but overall it was a peaceful experiment for me. Those feelings went away during the black screen so it's amazing when you are in tune with yourself and your surroundings how you can actually feel the difference or notice the difference of the runes working or "not". Even though they always work.
I did do the energizing runes, it was something I had gone through last night and drew on me. I noticed today that I had more of a pep in my step and was more productive throughout the day, and that is always great especially as I have chronic fatigue with my health issues.
