Creepy Interaction

This happened maybe 2-3 months ago and it just remembered it so I thought I might aswell post this here. Me and 2 of my friends (we are all black btw) were at the bench beside the library at around 9-10pm and we were coming home from football. We were walking towards the town hall and if you know where that is, you know the road connecting the library and the town hall can get very dark with that tree obscuring the street light. so as we are walking, were talking. Not loud btw but it's late and that road is quiet.

We see a woman walking on the other side of the road where it is very dark. My friends are still talking but i've kept the woman in my peripheral vision because I don't know, I just did. Im facing my friends walking backwards now and I see the woman just stop behind the tree staring at us. I panicked and told my friends to look at the woman discreetly and she's just hiding behind the tree staring at us. What made it even scarier was the fact that as we kept on walking, she mirrored us and kept rotating around the tree.

By then, we all started running. I was in genuine fear because was that a crackhead, was it a ghost? like wtf. As we've ran and turned left towards behind the bus stop,I glanced over to see if she was still there because I thought, "Its just a white woman scared of 3 black men in crouch end." I wouldn't have been surprised. Just before I ran left I looked over and shes still staring at us behind the tree whilst we're running away.

This was very weird behaviour and have never seen anything like it. Honestly for my own sanity, I wish she is racist and that's that. But every time now I go on that road or ride past it, I always remember it.

What do you guys think?
