Have you ever had a near death experience?

I was floating in a void. All around was darkness, but there was light overhead from an unseen source and I could see my arms clearly in the light. The darkness all around wasn’t actual darkness, but an absence of anything else for the light to shine on. Overall it was a sense of perfect peace, tranquility and contentment and a notable absence of any pain, physical or mental.

I was unhappy to wake up alive from it.
