Hi
Nixxy, welcome to the forum, my friend.
The dimensions interpenetrate each other, and thus we have what is known as "bleedthroughs," some of which are interpreted as "ghosts," others as "UFOs."
The hauntings that people experience and report are essentially due to the fact that
people are haunted, though few are aware of this, yet this concept has been growing in awareness, as can be seen in quite a few contemporary movies. In other words,
consciousness is haunted. Places that are known to be haunted are largely because people unknowingly keep feeding the astral ghosts, which keeps them around, often through story-telling and legends, such as old battlegrounds where ghastly images of soldiers may be occasionally seen.
Since we are also spirits, even while physically embodied, and everything is composed of energy, we are always attracting spirit energies. This is a natural occurrance. Hauntings are connected to what are sometimes called "parallel realities."
The corners of the eyes (peripheral vision) tend to pick up a bit more of the light spectrum, being that they are less trained to see in the particular way that most people are trained to see objects, which is to mostly notice things centered directly ahead.
How do you emotionally feel about the incident?
Best Wishes
