The following event happened a few nights ago.

I was lying in bed, around 11 at night when suddenly I felt the atmosphere change. It felt like an intrusion, lasted a few seconds and then showed up as an energetic bow of a dark yellow-brownish color. The bow turned on itself without closing in my opposite direction (towards the door) and disappeared.
There was no perceptible sound to my ear but my two cats reacted instantly and rushed to the front door to stare. So did I, but I could not see anything.
I live near a wooded area, in the county.

What could that have been?

It has happened occasionally before though not often.
