Kinda scared me

I live In a neighbor hood so there's a house directly across the street. Idk if they went somewhere, I haven't seen a car or lights on in days. I just get back from going to get oil for my car and I turn and see someone standing there. Not in my driveway, but in the driveway across from mine. It's dark, lights are off. So I can't see anything but the shape of a person. Like they were just standing still in the dark in an empty driveway. I'm obviously standing there trying to understand like are there people just there in the driveway chilling? No just one person is all could see. There's a lot of kids that walk around but their moms yell at them to come in because "it's too dark get yo ass inside"

And this person, starts slowly clapping. Still standing there motionless, clapping. So im like "bitch nah" and slam my car door shut, lock it and calmly walk inside and lock my door.

I don't feel in immediate danger. When I walked in, I went and looked out my window and the person was gone.

I feel safe so I'm not going to call the police, this person wasn't on my property and my man is home and that makes me feel safer. I'm fine. But it did spook me a little and I just wonder what that was about.
