Are the subconscious channeling sessions with our autistic client still of value, or are we making him focus on abductions too much, and starting to stir the pot by bringing the subject up again and again, at the request of the father?

You are seeing correctly here through your intuition that one can have too much of a good thing. Once the basic injuries from extraterrestrial encounters have been worked on and healing solutions provided, to revisit the scene of the crime, so to speak, can accomplish little in addition and may in fact reawaken inner fears by putting too much focus on it. So we would agree this is a good time to move on and address his concerns about his daily life experience and help to bridge the gap between what he settles for and what his family would like to see happen, and this would be a fruitful exploration of possibilities for him to widen his horizons on what to him is a very simple prosaic level but would bring tremendous joy and satisfaction from his family for him to open up and even have some simple direct communications. This is a goal very much worth attaining. It will help him to further adjust and to take on more and more responsibility for his own circumstances and his care. This will serve him in the long run, to be more independent in a functional sense.
