I don't know

 I genuinely don't know. The weirdness of my life continues.

Someone who is a fairly new acquaintance of mine seems to be delusional. I don't mean the joking "delusional" that you say when someone refers to another person as "they're my boyfriend!" when actually the guy in question is not interested in them. I mean delusional like actual, mental-illness-probably-requiring treatment.

As I said, I don't know the person well and I am going to elide details here, but fundamentally: they told me they had a very big problem they needed to tell me about (and of course, me being me, I thought "oh no, I have offended them in some way or done something wrong" and oh nope, and I wish it was because I could fix that). 

Anyway. The fundamentals of it: they and their disabled spouse are being pursued, someone wants to kill them, apparently because they're former law enforcement (I do not know them well enough yet to know if that detail is true, certainly, they are not working in that field currently). I mean, it seemed plausible. I know my eyes got big and I got scared and my brain was going "why on earth are they telling me this, there is literally nothing I can do to fix it" (they wanted me to pray for them, and I will, though perhaps not in the way they intended). I asked if the police had been called and they said no, their other relatives would be killed if the police found out.

For all my claiming I am a suspicious, cynical person, they had me going. I mean, I was standing there, scared, suggesting "well what about the FBI, they can sometimes secretly investigate things" and at every point they were saying no, no it wasn't safe. And they couldn't run because they couldn't get their spouse out safely and that person would be killed if they ran....

And they kept going and I was low-level panicking - surely SOMEONE needs to know, how can this be going on in our town?

And then they said, very quietly: "and they have something implanted in my head so they can sometimes hear what I'm telling people" and then the penny dropped.

And I admit: I know I have a bad poker face, because I must have looked incredulous, the person said "I'm NOT crazy" but....I don't know. Putting the pieces together in a calmer moment it does seem pretty standard delusional to me

The problem is, as always: what do we owe to each other? This person has a spouse who, while physically disabled, seems mentally sharp enough and I think they might realize it (based on other things they've said). I don't know whether to contact mutual friends or....what....or if this person has told other people this. I am NOT calling law enforcement because to me the threat doesn't seem real. (I know, I know, if some part of it turns out to be I'll feel terrible if the person is harmed but the implanted-device thing causes me major doubt)

Anyway. I'm tired and need to go to bed but it's going to be hard putting this out of my mind because I now have that ethical dilemma ahead of me. And yes, I confess feeling annoyed but intellectually I know this threat is absolutely "real" to the person, so they're not doing it to seek attention from me or to burden me.....but still, the burden is there and I don't know what to do
