orange florecent or glowing light the shape of a doorway seen above large tree , and feeling like something happened to us.

My husband & I were only dating then. We'd come back to my home to call it a evening and was sitting in the car in the drive. I knew the area well as I'd grown up in the same home. An empty field about 1 acre size joined our yard and at the S.E. corner was a huge cottonwood tree guessing around 80 - 100 years old ( a big tree) and just above the tree was a florecent (glowing) orange light the shape of a door. We could not see any beam, it was as though it was the light within whatever it was. Never seen light that color before or since. No actual craft shape could be seen, but the light never moved and could not hear any sound. I first seen it, almost like in a daze looking up at it, then like I came to and pulled away from my husband and said look. We both looked up and we both looked at one another and looked back up and it was gone. As strange as what we saw, was also the way we both felt afterwards. We were both so tired, I went straight into the house and to bed, unlike me to do, and now husband, could'nt even make it back to his home, stopping a few miles down the highway stopping at a rock quary and sleeping in his car. Not normal. We both felt as though something may have happened to us but don't know what or how we'd ever know.
Date is approximate.  PD
