Conversation: The conversation between human and AI assistant.
[|Human|] My husband has fallen asleep twice today for a short period of time and when waking up does not remember anything that has happened in the last 24 hours. He does then remember after being awake a few minutes. He has been under a lot of stress. What could be causing this? I am very worried. He feels fine. No pain
[|AI|]  Is he taking any antianxiety or antidepressant medicines? Such can happen under influence of medicines. Also, sometimes soon after awakening from sleep even normal person can not remember for little time. Also sometimes there can be some hallucinations while going into sleep and waking up from sleep called hypnagogic and hypnopedic hallucinations. But if he remembers everything after little time, it's not seem worrisome condition. Still I advise you to get him investigated (MRI Brain, thyroid function test, Serum vitamin B12).
