A weird cylinder object with lights flew over me and away.

I was on the sidewalk walking my dog in my neighborhood. I heard a really weird and quick sound from above so I looked up into the sky. While I was looking my dog started whimpering and tried to go back to our house. I saw like a cylinder shaped above just floated away. There were lights that would change color super fast until it went back to white. I thought it might be a plane until I looked it up, it was definitely not a plane. To my eyes, it was blurry around it and it was foggy. I went to check my phone to see the time, it said 4:20. I left my house at 4:10 and had definitely been walking for 20-25 minutes. It didn't make sense, my phone then shut down while it had a full battery. By now my dog had been really tugging, so I walked back to my house. When we got home my dog ran into her crate. This is super weird, she hates going into the crate and never goes in it.
