If any of you have actually been abducted...then i would pose this question to you: Have you ever known that "they" were there with you but you couldn't see them? Has any of you ever had something done to you while you were awake but those doing it were invisible? Have ghosts ever been done to use needles on a person similar to an injection? I'm just curious...

Cat - personnally i don't believe in abductions, so the answer is no.

Reading between the lines though, you seem to be asking this question for a reason - do you feel this has happened to you?

probably has, since the topic is sightings, reports and experiences.
