Just needing to talk

Last night and today are sad days for my hubby. Last night he told me he was trying to nap and something jumped out of his shoulder and hit him in the back of the head. I said no honey you must of been dreaming, he had a hard time accepting that answer. Then wanted to talk to his dad about it, had to remind him his dad is no longer alive. He cried for at half an hour. He has cried off and on today, says he will never get better. Im wondering if he is going through withdrawls, we are wiening him off the narcotics he was on for the saceriliac joint pain he had. I never know what to say when he says strange things because I know it is very real to him. I hate not knowing how to help him.
