Yes, I know Swedish and German, and this is the case for those words, as well. The "input" is irrelevant as long as it ends up with my thinking of the concept of "Friday" or whatever. In the case of foreign languages, foreign word goes in, "Friday" idea/color comes to mind. It's also the same if I look at a date on a calendar and see that a certain date is on a Friday, but not with the specific word "Friday". Of course, this is the same case for all the other days of the week, numbers, and the few letters. What is also interesting is if the "input" is a color very similar to the synesthetic "color/idea" for "Friday", I will also immediately think of the word/idea for "Friday" (in English). So it sort of can go back and forth.
Also, I will say that as individual letters or numbers "disappear" into a word, I do not get the synesthesia associated. So like "fourteen thousand" does not trigger the synesthesia I get for those individual digits, nor does "Amnesia" trigger my "strong" synesthesia for A, M and N. I hope this makes sense. I'm really trying to describe it as best I can.
You used the words 'mindset' and 'undercurrent' to describe these sensations. Do the sensations occur visually taking space and having orientations? If you think of trigger concepts sequentially do the colors align to form a spacial sequence. Is there any way a normal person can understand what you 'see'? Anyone here who can add something on this because its a fascinating aspect of our consciousness.
I'll try my best. Okay, imagine a bicycle. Question: 'Where' in your mind did that happen? How was it 'oriented'?
Next, imagine a bicycle. Now imagine an orange. Now imagine a vest. Now imagine a bicycle. Question: Was there any sort of "spatial sequence" or alignment thereupon? Try that sequence again, but imagine them along some "orientation" or "position".
Now, imagine a bicycle three meters behind you.
See what I mean? This is exactly how synesthesia happens for me. Most of the time, the "sensation" is just there. Formless, positionless, orientationless, in the "cyberspace" of my consciousness. It's possible to give the synesthesia "orientation" or "position", but most of the time it occurs to me wherever its synesthetic counterpart occurs, usually with the same "position" in my internal operating "cyberspace". This is what I meant earlier when I said something like "when it's there, it's just there, but if it were on my left hand, it would be on my left hand"...
I hope this makes sense for you. If it does not, feel free to ask me whatever will help you understand, or give me directions for how to explain it like I did.
