Invisiblow

This is my far real experience about Minecraft.

I was searching who someone in the server who would visit our base, but one guy was busy. In fact, no one wanted because they were busy. It sounded weird, like they were building their bases (or something) too. I wasn't waiting for too long. I asked again (because someone didn't reply) and an active guy (who once visited my base) replied. He wasn't busy.

But, soon, sooner than soon when I asked, something shoot me with a snowball that kicked me far. I know where it shoot, but I saw a half of the snowball in the right side of the screen, so I was searching in this place. Nothing.

As if something invisible shoot me. I had a full health and when it shoot me I had half health. Hope it doesn't happen again. This is the place where it shoot me. I call the invisible entity Invisiblow.
