We figured out he was hallucinating due to an Ambien he took the night before. The effect lasted 2 days. We figured it out the 2nd time it happened. Their immune system is very low and medicines the might have taken before without side effects, may cause them now. Also we found a way to attack the pain, it really worked. Its an injection but i dont know the name in english. If your interested let me know i will find out. Good luck!!
