"On July 17th, 2011 Myself and 5 friends were sitting along Municipal beach shore having a fire around 2-3am. When we noticed a glowing green ball of light in the water, Pretty close to the shore a few metres out just below the surface; about the size of a grapefruit. It started to drift out and pulse. We were trying to come up with any explanation for what it could be, like something in the water reflecting off the fire, but nothing could debunk it. Then all of the sudden a dark circular shape surfaced out of the water (it looked like a bald head/shape) too dark to see details. So my friend swam out a bit to go see.. And it goes back down. The light comes back.. Drifts out further pulsing. This happened a few times gradually moving out further. We were all in shock, trying to record with our phones but it wasn't picking up. I honestly have no explanation for what we all saw. It was definitely something intelligent with the way that it was interacting with us. Has anyone had a similar experience?"
