When I was a small child, I often noticed "shadows" lurking around trees where I lived, and always lurking just around the corner from people who were upset.

The first time I had orgasm I knew nothing about sex in any adult sense, but afterwards ran out and hung in my tree swing in the trees that the shadows preferred, and I remember them they were very much squirming like worms feeding on me there. Later, I would practice things like long distance running and fasting, and notice the contrast between that and some more infested states if I was masturbating.

I am not celibate, but I am aware of how sex is an important and delicate subject when it comes to energy, because it is usually a main feeding point of a type of non-physical alien force. Sex needs to be done with a certain awareness in that light, and if shadow creatures are perceived, then they should be dealt with up front and not just accepted or ignored.

Energetic seeing is not with the eyes but is a tacit feeling as clear as seeing, but with much more depth of view. Two seers from different angles into the crystal lattice, different but equally real realities. In describing those realities colors form and movement are used by the seer as metaphors, but close metaphors to a common view among seers if they are good ones.

as far as muddy blue as a metaphor for the energy of this class of being and those they inhabit, could be muddy blue like you say. Seems to fit better than any other color. However when I see these entities, the extra chakras and all first a foremost by the unusually long tenticals that these types extend out from themselves, and reach inside your energy body to look for any niche that might be favorable to attach to. From men these tenticals extend mostly from the solar plexus, from females they come vertical down out of their underside and extend out from there.

Small children do become infested some times and when I see that in them it is disturbing, it can be more disturbing than seeing an adult predator for instance. The predator will invest a great deal of energy to infest the young if they are able to.

That is why although every person automatically sees energy directly like we do, as the original impression, most people do not want to be aware of it, because it is more often ugly or disturbing what a seer or empath will see, rather than sweetness and light, which may be a rare experience to a seer.
