I wouldn't say you had a vision , more like a lucid dream about something you admit you were terrified of as a child and have an interest in now , if you had a fear of ... lets say clowns ... then the faces you would have seen would probably been of clowns .
Neither do I think its an indication that you were abducted as a child , if you had been I would imagine you would have had many dreams about the abduction in the years since it happened , and the dream would have contained details associated with it .
I must admit I have always enjoyed lucid dreams whether they be good or bad , the way they stay with you for the rest of that day rolling around your mind.... its as if your brain's trying to tell you something
