need help understanding please

A friend of mine told his wife 4 months ago he was a lightworker and had always known he was here for a higher purpose. Told her he was taking time out to expand his spiritual awareness. Locked himself in the computer room everyday, stopped communicating with her except to say things like I can't tell you what happened to me you'll think I'm nuts.He would call his wife to see a video from youtube and then when she went with him he'd tell her she couldn't see it because there were subliminal messages in it. He told one of his children that an alien entered his body thru his head, made his head bubble and that the cat started licking his head where it entered, He started waking them up in the night to come look at the sky which they agreed the moon was now not where they were use to seeing it.He was acting like he could see things in the sky that they could not see. He came out one night looking terrified and told everyone that he had amazing pain in his heart area but explained no more and back to the computer he went always locking himself in. He started telling them he was seeing 11:11 and that he was activating his dna coding. He started filing in forms for on line dating services saying he lived alone and was single or divorced ran up 8,000.00 on the credit cards and said money doesn't matter just imagine what you want and it will come. Then he came out said that their vibrations were to far apart and walked out on his family. Refusing to talk to anyone other than to say they are unresponsive unaccepting and no longer on the same vibrational path. Does anyone have any idea what may have happened. This family needs help and I have no answers for them. Peace to all.
