My husband has been having hallucinations? for the past about 4 months.  At night he awakes and then wakes me up to find out who is in the house.  He says he heard the back door open and someone come - no one is there or has come in.   When he is sleeping at night he breathes normally and then doesn't for (it seems like forever) and then he takes a deep breath and so it goes.  He doesn't have sleep apnea.   He says he sees little men all dressed in green pruning our neighbors shrubs and trees.  I don't see them and then he will tell me they aren't there now.  He has been accusing me lately of tampering with his computer to monitor what he is looking at.  He has me searching his computer area for things that aren't there like little monitoring devices.  He has become angry several times because I tell him I don't know what he is talking about.  And then suddenly he is just his normal self.  Sometimes his answers aren't appropriate to the question.  Sometimes he just talks words, especially at night.
