I was about 19 years old living in Orlando, Florida and had recently moved into an apartment with my best friend, Carl, his wife and their 1 year old son. We had the 3rd floor which had the stairway outside (instead of an indoor staircase) and it faced the woods. There was hardly any lighting back there and it was sometimes hard to navigate in the semi-dark. But, in the beginning, everything was great. However, soon problems began between his wife and me. So until I could find another place to live, I always made sure I came home late after they all went to bed. When I was home and she was there as well, I always got this weird vibe from her. She just made me very uncomfortable so I tried to stay away.
One evening I came home about 1am, like always, it was very dark outside my building. The lights in the hallway leading up the stairs were very dim but I never thought much about it until this night. I walked up the stairs and to my front door where I began to put my key in the lock. As I leaned in closer, just as I was about to insert the key, this very strange blue light came out of the keyhole. As it leaked out it formed almost a ball but before it was complete it sucked back through the hole. Almost like the back draft of smoke from under a door. It all happened so fast, and I was tired, I didn't believe what I saw... Thinking I was only imagining things and making excuses for the light such as... It was only static electricity or something.
A few days later, I was sitting on the floor of my room packing up the entertainment center when something caught the corner of my eye. I looked to the left, directly into my bathroom and that same blue ball was now hovering in the dark. There were no lights on in the bathroom and the blue ball lit up the whole room. As it was hovering, it swayed slightly to the left and right a few times then went rapidly went to the far side of the room. I couldn't see it anymore from where I was sitting so I got up to get a better view. Before I even made it all the way into the bathroom, this thing goes flying through the bathroom towards my shower curtain. It hits my shower curtain, which makes a little fluff, and then disappears. I knew I couldn't be dreaming it, and my mind wasn't playing tricks on me because my shower curtain is moving.
I left that apartment shortly after and never saw the blue ball again. I never did find out what it was. No one I've ever asked knew either. If anyone does know, please! Please! Tell me! I'm still curious!
