He has awakened me during the night coming to my side of the bed while he is trying to find the bathroom. (The bathroom is the other direction close to his side of the bed. This afternoon I returned to the family room to find him standing and peeing on the floor. He thought he was in the bathroom. Am I dealing with more than CBS here? My heart breaks for him. Who should I talk to? What can I do for him? I remained calm and helped him get to the bathroom to finish, cleaned the floor. I don't think he remembered it later. He had the "look" he gets when he is having a CBS hallucination. He's experienced significant vision loss due to glaucoma. I first noticed the CBS hallucinations about 6 months ago. He's not incontinent -- it's not incontinence.
Now - on the other hand - when she had delerium due to an infection, she was very confused & had similar type hallucinations.
But, it was very obvious that something was wrong and she required hospitalization due to her altered mental state for the infection. (She had a UTI and Cellulitis)
"People with CBS visions usually come to realise that the images are not real - that they can't touch them and they are 'mirages'. In medical terms they are illusions (false images which the person knows to be false) rather than delusions (false images which the person firmly believes are real). In a Canadian study, 8 out of 10 of participants knew that the visual hallucinations were not real after the first episode, and 9 out of 10 by the second, although a few did not realise until they had experienced 10 or more episodes.
At first, however, those experiencing the hallucinations may think that they are real. They may prove to themselves that they are not by turning on lights, or by reaching out and attempting to touch the images. One patient described trying to fight off the images of wild animals by using an umbrella."

You say he didn't remember the incident later. At the time, what did he say or how did he respond when you explained he wasn't in the bathroom?
