I was walking down the upstairs hallway and noticed a very bright light in the air. It appeared to be within one or two miles of me. I observed it and the movements it made were not like any that current aircraft is capable of. Also, there were no anti-collision light or strobes. Just a very bright light. At first it appeared to be flying two miles away, parallel to my road, but within a minute it changed directions and was heading straight for me. I didn't know what to do so I ran to grab my phone (only took 15 seconds) and when I came back, no craft. By the speed it was moving and the position of it in the sky, there was no way that any normal aircraft could disappear like that. To make it even weirder, I asked Siri on my phone, and used an aircraft tracker app, and both told me that no aircraft was visible in my area. I came back minutes later and noticed nothing in the sky, but did notice more air traffic than usual during the day, only hours after the sighting.
