I have two EXTREMELY vivid recollection of UFOs that I saw. One as a child of ~6 years of age which I know is true because another witness said it was a signaling flare before I knew what signaling flares were, and as my grandpa correctly pointed out, it looked NOTHING like a signaling flare. The second one is much later, from a time I was obsessed with UFOs, and I don't know if I really saw it or it was a dream. It just bothers me so much that I can't recollect if it was all a dream or not and that I've had this memory for so long.
