Are we talking about hallucinations? If so, marijuana is not a good drug if thats what your looking for since it doesnt cause you do imagine such things. (unless you make yourself believe so). But my vote goes to visual tho.
i guess you can still see lots of colors and blurry stuff...not really hallusinating...but damn man that's a good question....i pick both
beyond the old 'would you rather be blind or deaf', i dont think you can compare auditory to visual stimuli. visual stimuli is more primarily used by the human mind so it would be wise to chose sight, but the optimal visual stimuli goes in harmony with sounds that come with it, vice versa.
I think we're not giving our brains as much credit as needed. Audio triggers so many things in the brain. We may value our sight more than hearing because we believe that what we conciously percieve is more useful, but all we're using it for is navigation and evaluation. Audio cues do that too. Reaction to vibrations vs. reaction to light.. hmmm yeah it's a tricky one. Just like a STOMP! concert! yayaya
its not as simple as that. vision is the primary sense of humans - we have genetically invested the most conscious link to vision because not only do we use it for navigation, but more importantly, manipulating our environment. using tools, making tools, interpreting emotion. sound is more secondary. sound will be interpreted through the boundries set by our vision. for example, there is a little trick that demonstrates this. a screen is shown on which is a mouth. a sound is played, and audience asked what sound is made. even with the same sound coming from the speakers, if the mouth says 'da' then we percieve 'da' if the mouth mouths 'ba' or 'ga', we hear 'ba' and 'ga' respectively. the actual sound percieved is the same in all cases. this could be that the audio hears the sound correctly, but when it comes to interpreting the sound, the conscious takes preference for the visual cue; or when the sound is being processed, it does so through the expectations of the visual field - ie we see a mouth make the sound ba, and a sound comes out so we interpret this sound as being the one that was made by the mouth we saw. either way, vision takes preference. this is just one example but there is a larger area of the brain set to deal with visual cues than any other, as well as vision being the most intricate sense. thus it is easily proposed that vision is the primary external sense of the human.
audio is more for signalling, and recieving signals or warnings. if we hear something but cannot see it, it is more frightening than seeing a silent entity. we use audio to alert us to things to look at, one could say. audio is of course rather diverse for humans in todays world but it remains secondary in helathy, fully sighted humans.
auditory hallucinations always fuck me up way more because im always trying to find out what a sound is for like an hour then realise it was never there.. where as visual i can go along with just fine.
I enjoy a combination of both. I remember a few mushrooms trips I have had in which I was looking at someone and their head and face were morphing and they were talking to me. While I was listening to them, I was so tripped out I heard them stuttering. They weren't really stuttering, but it sounded like they were. It was like hearing a scratched CD playing when it just gets stuck on one part and won't play right. Anyway, the two compliment each other nicely.
The strongest visual effects Ive ver goton form weed was smoking in the deep woods in the summer, every thing light up and got much brighter, was more intense than I thought could happen on weed.
I prefer auditory actually. Sometimes when I smoke at night a song will start playing in my head, but it's usually really complex. Like there will be a whole range of voices singing, or else it will go in a round. lol
