Q: (L) I read in a book about a monster called the "Beast of de Beauvan which appeared first in 1764 and was supposedly done away with in 1767. Who or what was this
beast?
A: Other dimensional "window faller."
Q: (L) You mean it fell into our dimension from another through a dimensional window?
A: Yes.
Q: (L) Well, that would explain a lot of things about it. What about the creature known as "Spring Heel Jack" who terrorized England some time ago?
A: Same.
Q: (L) What about the Mothman in West Virginia?
A: Same.
Q: (L) So, windows to other dimensions are the explanation for a whole host of strange things?
A: Yes.

Q: (L) Okay, can we ask now about El Chupacabras?
A: It is what it is.
Q: (L) It is a 'goatsucker.' Where does it come from?
A: Review transcripts re: "window fallers."
Q: (L) If it is a window faller, does it come from another density, or a lateral dimension?
A: Closer to the latter.
Q: (L) Okay, so it is like a horizontal dimension. What allowed it to enter our realm?
A: This is complex, but best described as "EM wave bursts along frequency border variation."
Q: (L) Is there some way to capture or stop this creature?
A: You do not yet completely understand all the "mechanics" of the window faller phenomenon. The physicality is entirely transitory and partially dependent upon consciousness variabilities, as well as expectations of witnesses.
Q: (L) Does the energy of the fear of the witness enable the creature to continue its existence? Does it feed on the excitement and fear, and is that what makes it manifest?
A: Close, but off a little. It is the other way around, and retro-factored by one half.
Q: (L) What do you mean by that?
A: It is mutual, rather than unilateral. Also, remember that a window falling represents a cross-energizing of realities, equally represented from each "dimension" in question.
In other words, because the dimensional curtain has been "torn," half of one and half of the other contributes to the whole reality.
Q: (L) Does this mean that something from our reality is also scaring something in that other reality?
A: No, it does not "work" that way at all.
Q: (L) Is there any possibility that this mutual creature is going to turn its attention from animals to humans?
A: Ditto last answer. And review response prior to that!

In perhaps the most compelling account, military divers in Siberia's Lake Baikal, the world's deepest lake, encountered "a group of humanoid creatures dressed in silvery suits" at a depth of 160 feet. Three humans died during the ensuing chase.
