Blue Bioluminescent like object that appeared to be "swimming" across the sky.

At the time of the sighting, I was living out of my car, parked outside of a friend's house. At night, I would often look up at the sky, for hours at times. This particular night, I was outside with three other friends, just talking and laughing. I look up and notice what I can only describe as an unknown flying object that appeared to be "swimming" across the sky. It was big, lengthy, and it had this Bioluminescent like blue to it. I immediately try to get the others to see it also, but they all seemed to either ignore me or not hear me calling for them. I called out for them again, and still nothing. At that point I looked back at the sky. There was something "calming" to it. It faded/disappeared into the night. Soon after, I went into my car to sleep. The following morning, I open my eyes to the sight of deer, across in the neighbors lawn. One in particular, was making eye contact before returning to eat from the lawn. That day was a very important day for me, and I had been anxious for this day to arrive for weeks. As for the sighting, I never mentioned it, in fact, this is the first time I'm sharing this story.
