Does body tremor, jaw relaxation, tongue protrusion, body coldness, cessation of breathing, emitting a snore, then loss of consciousness and awakening after a few minutes, mean a visit from the Angel of Death?

There is no evidence to suggest that the Angel of Death visits the son of Adam in the state mentioned, even though there is evidence indicating his general visits, such as the hadith (definition): "There is no household except that the Angel of Death visits them once every day," which Al-Albani graded as weak. It is also mentioned in the Sahihayn the story of the Angel of Death being sent to Musa (peace be upon him). Occupying oneself with this type of matter, from which no reward is gained by knowing it nor any sin by being ignorant of it, is not befitting for a Muslim.
