Hi - I had an experience that started in a dream where i met my 'spirit guide' - I've never been aware of one before but that was who this character was in the dream. He took me to a place and said 'this is where old souls sometimes come when its time to die'. He then showed me forwards to go on alone. It was like stepping through a portal or something out of the dream world where lots of things switched all at once - I came out of my dream body and felt like I was just a tiny point, the whole surroundings shook and vibrated like the whole world was shaking apart, all kinds of moving shifting light appeared around me, beautiful sounds were all around me - all shifting and changing constantly in tones and all so loud, also I felt like i was rushing upwards, and also a feeling of very strong love. It also felt like i was moving towards the source of the love and as I did so everything got stronger (light, sounds, feelings etc). And the source of it felt like an aware being (god?) in the way you can sometimes feel when someone has their attention on you, but it was a purely loving attention. It quickly got so strong that i heard myself say 'i can't take this any more' and I popped out of the whole experience and was sitting upright in my bed (which has never happened before either.)
This happened about 10 years ago - 10-15 years after I started meditating and doing chi gong etc. Since then I often think back to it during practice or just in general. I also get weaker versions of the sensations coming back sometimes in practice, but nothing near as focused or intense. Also its only really the feelings, not the lights or sounds. And yes its also awesome and fulfilling and definitely helps spur me on in practice.
