It is very interesting to hear of all of your experiences with synesthesia!
I have a very hard time explaining my synesthesia to others, but it is very pervasive in my everyday experiences.
I have synesthesias involving a crossover of texture and smell/taste (from either direction).
This can be pleasant if I touch a fabric that is quite smooth or silky (it slightly activates my salivary glands)--or if I smell something wonderful in the air (I can feel the texture on my skin and sometimes feel cocooned in it).
However, there are certain textures and smells that I avoid all together, and I can quickly become overstimulated and completely shut down. For example, I have strong phobias of cotton balls and frozen foods (particularly the icy layer that sticks to one's skin) that completely send me into a panic. I am unable to wear scratchy clothing for this reason. I can taste AND feel the horrible textures (so it feels like I cannot get it out of my mouth or off of my skin)-- and I often get a gag reflex paired with goosebumps. Just talking about it gives me the heebie-jeebies! Strong smells (perfumes, chemicals, etc) have a similar effect where I tend to feel coated in the stuff, unable to get the taste/smell out of my mouth and nose and the texture off of my skin.
As a side note, like a few others here, I also see pictures in response to music.
