There's this humanoid figure that's constantly present in my dreams.
In them, it's always beneath turned off street lights or beneath turned off light spots, so that I can either only see its vague shape or sometimes just their presence. But it's not aggressive, it's never done anything harmful itself, it just stays there watching me from afar, though it causes fear in my dream self. However, I've noticed a pattern in dreams/nightmares it's present: they all take place at night, and as the dream progresses more and more street lights/home lights get turned off, which by definition "expands" the dominion of the monster (?). Sometimes, though rare, the dream will start lively and in bright daylight and then suddenly switch to the usual eerie night scenario.
Though not directly correlated, in a lot of those dreams something violent will happen, for example: getting robbed and shot at, escaping a school shooting, watching a gory street accident happen right in front of me, or at the very least, walk alone through dangerous streets on my way home.
The creature has the consistent shape of a very tall thin human, sorta like slenderman or SCP-096, but again it's a neutral stalker that's never done anything bad.
