I believe there is. I have no evidence for this claim so I do not expect a single other person to change their mind as a result. But my experiences have repeatedly shown me that, when I felt my consciousness fading or my life in danger, I felt a connection with all of the love I had felt, a connection to the rest of the universe. I felt a peace, as the separateness that was my mind faded into something greater and more palpable.
Scientifically, this may not be that likely. But it accords with what I've seen in the world and my sense of its logic.
