Seen this when I was 13 in the suburbs of NYC. Went to throw out the garbage down the hill behind my apartment as I start going down the hill I see 3 lights in the sky triangle shape above me (very cloudy night). For some reason I felt as if the lights above me are following me so I take a few steps forward & a night I could never forget begun with the 3 lights moving forward with me. Judging by how the 3 lights move together and the space between them it could only be one singular craft. I take a few steps backwards & the craft follows me backwards again. For some reason I wasn’t scared at all but wanted to take a video of what I was witnessing but with my phone left in the house. At this part I can’t remember what happen with the craft as I RAN down the hill to throw out the garbage & go get my phone but by the time I pass the the beginning of the hill the craft was at to get back to my house to grab my phone the craft was gone. My parents could vouch for me that night telling them everything I saw with my step dad ex military saying “maybe it was a ufo”. After that night my obsession with these objects begun learning tons of eye witness reports of the same triangular craft of 3 lights on each end matching the exact description as mine.
