What you described sounds like an experience known as "dissociation." Dissociation is a psychological defense mechanism that some people may experience in response to traumatic or overwhelming events. It can involve feeling disconnected from oneself, the environment, or reality. One common form of dissociation is an "out-of-body" experience, where a person may feel like they are observing themselves or their surroundings from an external perspective, as if they are watching a movie or looking down from above.
During extreme stress or trauma, the mind may dissociate as a way to cope with the overwhelming emotions and sensations. By disconnecting from the immediate experience, it creates a temporary mental distance that can serve as a protective mechanism. This is the mind's way of trying to shield itself from the full impact of the trauma.
The fact that you have no memories of the event could be a result of the mind's attempt to protect you from the distressing and traumatic memories associated with the event. In some cases, dissociation can lead to memory gaps or amnesia for certain aspects of the event.
It's essential to recognize that everyone's experience of trauma and dissociation can vary. If you have gone through a traumatic event and are experiencing distressing symptoms or difficulties in your daily life, it may be helpful to seek support from a mental health professional. They can provide you with guidance and coping strategies to help you process the trauma and its effects in a healthy way. Remember, you are not alone, and there are resources available to help you heal and move forward.
