No, It is not a catagory of items, I made it a catagory(1 million revisions),
My intention with making that synesthesia was to get one of the best memories in the world if not the best memory,
Can you explain how a person can get synesthesia by imagining(?) the taste of sounds,
I will try to experiment with designing the 1 million revision synesthesia using your method but will use a 5 times revision synesthesia just to be safe as I think that the brain may have to do a dangerous amount of processing for a 1 million *revision synesthesia,
And I will try that method on myself,
I know little of applying synesthesia, But I can design them using whatever I know,
It will be interesting to see how will thinking in synesthesia feel like(I tried thinking in smells, Like people think in sounds and images) and it worked but was meaningless(Those smells had no meaning) but I think that they can also be used in memory as in many memory techniques people say certain things in their imagination but by adding meaning to smells as a person has added meaning to images people may be able to smell meaningful smells when visulising through their mind’s nose and as olfactory memory is the strongest memory which is the memory for smells a person may even be able to boost retention with this method and using a method of smells has increased my performance in the memory leage by 20% and I will use olfactory memory because of this for the foreseeable future and I also hop to use sound memory for memorizing(Ex- As soon as a difficult number comes like no 34 -A different voice will be imagined dictating the numbers which will be converted into images but this method still work in progress and I hope to use it with the Olfactory Memory technique as I think that the content of the speech not the sound of voice giving that speech consumes chunks of my memory which are very precious for me nowadays),
Have a Great Day.
