Well this is a pretty strange topic, I'm not sure how to introduce it or what forum it belongs in exactly. I'll just jump in:

Tonight, I realized that I am going to have to re-think my personal definition of "hyperspace." I think it's fair to say that in most of the discussions regarding experiences in hyperspace here at the nexus, it is understood that the primary aspect of the experience is visual. Or at least, people usually seem to focus on what they saw, what things looked like -- even what is remembered as physical movement is not usually actual moving of the body, but the visual representation of movement in the mind's eye. (I want to say here that I consider it no less real for having taken place in the mind. Our physical bodies are frequently over the weight limit for carry-on luggage when Travelling, ho ho.)

But tonight, I had an experience which was three- (or four, I guess)- dimensional, and yet was almost exclusively auditory. I was listening to "Bits & Pieces," by Stoop & Fidget, a song featured in the legendary "6/04" set, but I have the entire song. It's important to note here that I have listened to this song literally hundreds of times.

Okay, so right away I heard something at the beginning I have never heard before. Elfspice has been known to do that for me; and it got my attention. I decided to just lay down and really listen to it. All through the song, I heard all kinds of stuff I had never noticed before, and every sound was not just an audible sensation, but a three-dimensional, tangible thing, almost an object. Some sounds came up to me curiously; some sounds lifted my hair as if in a breeze; some sounds brushed my shoulder. I began to get a sense of landscape from the music alone. Sort of like how you hear about blind people who use a kind of sonar to navigate. (making sounds, and using the returning echo to establish a physical sense of your surroundings.)

There are so many implications to this, it's hard to even collect them all and express them. Has anyone else had this kind of experience? Is hyperspace someplace you have to see to experience, or can you use "your mind's ear" instead of "your mind's eye?"

There is more, having to do with perceived changes in my auditory processing center -- I'll bring that up later.

I just started with spice last Sunday, but the six or seven times I've blasted off now, I definitely see less and sometimes no separation between sight and sound. There are sounds I can see and sights I can hear. I don't see any reason with as personal as the experience is that, for you, the audio aspect is super strong. Just my 2 cents.
