In 1975 I lived on James Island, S.C. I was about 8 or almost 9 months pregnant.

It ws almost dark and I headed home which was swampy and more isolated then on Fort Johnson Rd. James Island, S.C.  
This incident was in 1975.  I saw something hovering over the swamp, it was tremendous and had bight lights all over and around the top of a hugh disc, rotating around and around.  
I don't remembe a lot after that but I think I stopped the car and got out to go and look at the object.  I must have been there about 2 or 3 hours.  I think the object was glass or opaque in color and I remember that I was not afraid as many people say they are.  I don't remember a lot more and then I was back in my car and it was really dark about 6 or 7pm.  I had lost about two or three hours.  
I did not think much of it at that time and went home.  I did not feel drained, tired confused or anything.  I did not feel threatened either.
We had our daughter and called her laughingly our little alien child.  
I was alone so there were no witnesses that I know of concerning this object.  I think the object had an ability of letting us see it and then some sort of way of not being seen.  This was the only time I ever saw this thing.  
Thirty years later we took some photos of the little house we owned out on the island and walmart developed them.   A disc like object was seen in the left corner of the house.   I questioned Walmart and they said it was not any of their equipment, and they asked if my car window was down, and yes it was.  I still have the photograph.  
I am a retired nurse and also have a background in sociology.  
This was a strange event and I rarely talk about it, and I do not laugh at those saying they have had encounters.  ((name deleted))
