I have! Although never more than lights in the sky. Apparently there's a ufo base near where I live. Reports going back to the 50's, although not so many in recent years, so maybe they've moved on.

Btw the image you used of the triangular craft from the belgian wave was an admitted hoax, some young guy trying to cash in on some bounty that was being offered at the time if I remember correctly.

Not so off topic but I do however have some memories of weird abduction like dreams from when I was very young lol... I'm sure they were just weird nightmares I'm sure everyone gets though. I sketched a picture of the memory not that long ago I'll see if I can find it if you like :)
