That is, my experiences only happen in the present moment.

Josep- not so. All your (and my) experiences happen in the past. You can't even say you've experienced something until afterwards, but apart from tautologies, it's an experimentally measured fact. What's more, you continuously recreate experiences every time you remember them.

On an individual level, I remember my brother drowning. It must have been over 45 years ago, but the memory is still vivid. We celebrated his 60th birthday last weekend, with a really great ceilidh and sessions and walks. He was there. How so? It was a dream- but it's also a memory.
