It makes sense that you were triggered. You struggle with trust and you then found information that made you feel the stranger you helped lied to you. But... He could have forgotten his age. I've accidentally said the wrong age several times. He could have lied for personal reasons. Maybe it is a safety issue for him. He did give you his real name apparently. If I were going to do something nefarious, I'd use an alias. The likely answer is he's a quirky neighbor.

The rest of what happened could have been a hallucination or a woman walking around thinking about something. Or maybe she has her own mental issues. Lots of possibilities.

These two people coordinating some sort of ill intended experience against you is one possibility in a sea of many. It is highly unlikely. Try to remember that and go about your day normally today. You've done nothing wrong and there is no reason to believe anyone is plotting against you at the moment.

However, these kinds of thoughts are very much a symptom common for you. I know, I've felt them as well. Symptomatic thoughts resulting from a trigger is the most likely explanation. Strategically, it makes sense to go with that and work to find your way back to balance. Try not to fuel the other line of thinking.

This is a good set of events to talk through with your therapist. When do you see her next?

Hugs. We're here for you.
