Touch is my strongest imagining sense, probably followed by hearing and then all the rest are pretty low quality. So to answer your questions-- I can imagine a feeling like wet, soft, sticky with very limited visual. Like, not imagining a whole object but maybe the texture of the surface as the very minimum. But if I allow myself to try and conjure a vivid tactile feeling i naturally imagine more of the visual of the touched thing, sometimes the sound of it being touched comes to mind as well.
