There has been so much on UFO abductions, that it does make me wonder. I used to think the whole thing was kinda kooky, but I've known several very normal, sane people who claim to have had encounters.
My husband and I have some friends, two brothers, who although were not abducted, or anything like that, did witness some UFO phenomenon during the mid 1960's. Teenagers at the time, these men were riding dirt bikes in a field near their home. They were out a little late one evening and saw what they believed to be a UFO. To make a long story short, they gathered some evidence of a substance that was left behind and sent it off to be analyzed.
Much to the family's surprise, the legendary "Men in Black" showed up at their home, and at the school the following days, warning the family not to get involved. Both of these fellows were very hesitant to talk about this story even up to the present day.
My father-in-law, who lives in a very remote area of East Texas, was out in his yard the day the Cash-Landrum case occurred, about 60 miles away. He witnessed about 5 army helicopters tearing off to the area where this case happened. Several more people witnessed similar things that day.
There is a growing amount of evidence on this type of thing. It would be really interesting to put your husband under hypnosis and see if anything came of it.
