Anything is possible but the situation you describe is extremely unusual. It’s possible that you were intoxicated or using drugs and this could explain why you do not remember the event.
It’s is also possible that you suffered some kind of dissociative episode in which it could have been possible for you to send this e-mail and not remember it. There is a condition known as dissociative amnesia in which a person blocks out certain information, associated usually with a traumatic or stressful event and then are unable to recall any memories related to the event. People with dissociative amnesia report having long gaps in their memory and have no ability to recall anything involving the traumatic event.
According to the WebMD website: “Dissociative amnesia has been linked to overwhelming stress, which might be the result of traumatic events — such as war, abuse, accidents, or disasters — that the person has experienced or witnessed. There also might be a genetic link to the development of dissociative disorders, including dissociative amnesia, because people with these disorders sometimes have close relatives who have had similar conditions.”
I would highly recommend seeing a doctor or a psychiatrist regarding this situation. A doctor may be able to determine the source of your blackout or inability to recall this event. He or she may also be able to help you recover these memories regarding the events of that day. Please see a doctor to further investigate this disconcerting situation. I wish you luck.
