The Pink Sky

Hi guys I'm sorry to Disappoint you, the story that you are about to read will be different from the other stories that you've read on this site. So, I hope that you enjoy reading it:

This incident happened 3 years ago when two of my friends and I were going to our friend's home to eat dinner with him. When we arrived at his home he asked us to wait to tell his mom that we have arrived. At this time, I felt something as if it was coming to hit me from the sky, at first I thought it was a lightning but, there weren't any clouds up there. Then I looked up to the sky and I saw a small pink circle. After a few seconds this small light began to get bigger until it covered the whole sky with a pink colour. I was very scared and I couldn't move for a few minutes.

After a while, the light began to get smaller and smaller, then it stopped at its original size and after a few seconds the light started to move. The light showed some kind of flame behind where it has left, it was very fast.

Until this day I don't know what it was and what does it mean?
