Shadow figure in my flat - recurring visits

This has been happening for about six weeks now. I live in a Victorian flat in Clapham, built 1895, and there's a presence I can't shake. Most nights around 2-3am I wake up feeling observed. And I'll see this shadow figure standing by the bedroom window or sometimes at the foot of the bed.

It's not aggressive - it doesn't touch me, doesn't make noise, just... watches. For maybe 30 seconds, and then it's gone. I'll turn the light on and there's nothing there, no explanation. But I absolutely see it. Not dreaming, not sleep paralysis (I've researched that obsessively). I'm awake.

I'm not religious but I'm starting to think about getting a priest involved or something? The whole thing is deeply unsettling. My girlfriend thinks I'm sleep-deprived and anxious, and honestly maybe she's right, but this feels real in a way that anxiety doesn't.

Has anyone dealt with recurring shadow figures? What did you do?

Before anything else - get your iron levels checked. Anemia causes hallucinations and a persistent feeling of being watched. Also check your medication if you're on anything. Some SSRIs cause visual disturbances, especially at night. Boring medical answer but if it's not that, then you can pursue the paranormal angle properly.

Shadow figures are genuinely one of the most commonly reported phenomena. Good news: they're almost never hostile. Bad news: we don't really know what they are. Could be residual haunting, could be interdimensional, could be psychological. The fact that it's regular suggests it's not random.

Clapham's got history - lots of old buildings, lots of lives lived there. Victorian era was when spiritualism was massive in London. Possible you've got a curious spirit who's attached to the flat rather than to you specifically. Have you researched the building's history? Previous owners, deaths, anything significant?

I'll turn the light on and there's nothing there

Try keeping a record. Every time you see it, note the time, what you were thinking about beforehand, what it was doing, how long it stayed. After a few weeks of data you might spot patterns. Is it triggered by your emotional state? Specific dates? That could help figure out what it is.

Protect yourself emotionally first - don't feed it fear energy. Sounds new-agey but genuinely, if you're frightened, it might reinforce its presence or your sensitivity to it. Tell it firmly but without aggression that this is your space. Set boundaries. Sometimes that's enough.
