I have Greylock thoughts;
As someone who has a thoughtform companion and is very deep in the spirituality of the unconscious mind, this series... Goes back and forth for me.
One; implying that thoughtform are inherently evil or unpredictable is a wild ass idea that I dislike. Thoughtforming, even if you don't believe the thoughtforms being real, is a very real practice and point of comfort for some people. Tulpas are literally a very important spiritual and religious practice.
BUT... That leads me to--
Two; these thoughtforms are made hastily and without the meditation and regular concentration of the thoughtformer, so perhaps the sudden creation and sudden severance of their metaphorical 'umbilical cord' is why they become the way they are. Specifically with Katie, the kid murdered by her 'imaginary friend', I don't think they're actually contained. I think it went to look for it's 'parent' and... The trauma of such a rapid birth from nothingness to full awareness took over and it lashed out in anger.
Imagine, for a second, being nothing. Absolutely nothing. That's what it's like being conceived. There's nothing for a long, long time. We are eased into the world. First, in the womb, we make out faint sounds and muffled lights. We have no sense of self. We have no empathy, we have no concept of the horrors when we're born. All we know is bright light, aching lungs suddenly breathing air, being grabbed, held, smelling for the first time, loud noises unmuffled by the womb. Even unknowing, unaware, we're born screaming. No one remembers what it was like to see for the first time. To hear for the first time.
Imagine what it was like for these thoughtforms, ripped straight from sheer nothingness into bright, screaming, aching awareness. Immediately knowing they are something. Someone. Just... Suddenly existing, with no womb to soften the blow.
The masked one throws a wrench in that, as it appears before simiodyne and it's machine, but it could very well be the manifestation of someone very vengeful or, as one of my favorite YouTubers implies, maybe it is the manifestation of humanity's subconscious evils. Now, said youtuber just said subconscious, but I think we have to specify evils because I don't personally agree that humans are inherently evil.
