I was cleaning my car out at the at the park at Lake Michigan. It was 7:30pm, and there were no other possible lights that could shine on the water. They were floating, then some went under water, and came back up. They seemed to be in some type of formation while they were swimming. They would swim 3 and 3, come together, then separate, while 2 went up and down. They others stayed above the water. I got a feeling as if I caught something I was not supposed to see. When I snapped the picture they swam away fast and disappeared. You can’t make this up.

I was sitting in my car about to go into the office I work at in a suburb of Chicago. When I noticed a bright reflection coming from an object in the sky. I noticed it moving oddly as if it was tumbling end to end but didn't seem to be falling but flying on a relaxed [landing]. Didn't seem to be moving quickly but hard to tell as I couldn't determine size or proximity. I thought it was odd so I quickly pulled out my iPhone 7 and took a photo burst (the mode my phone happened to be on already) It then moved out of view behind some foliage.
