I just said grandma's it could have been anything really.
I will say I don't experience sensation as separate from myself. It's almost always linked to some past impression. I went sky diving once and it felt like when I went on a roller coaster, while when I asked the ILI I went with she just said it felt like rushing wind. But I'm Se PoLR. I imagine Si PoLR would have a hard time associating sensations with past impressions. I imagine Ni would override and just create an archetype out of the object, or reduce the sensation down to it's most basic form, in a way making up for Si. "Touches rock, feels hard, like all stones." or something like that. Or maybe they have a hard time noticing all the different sensations but have an easier time reducing them all to one basic core sensation, like out of all the data they just leave only knowing the essential info? Not "Touches rock and it feels jaggedy like the rock's in my cousin's backyard."
I've seen Se types smell something foul they always say "That smells like shit!" even when it doesn't actually smell like actual shit, and for me it's usually like "That smells like rotten eggs/ cow maneur/ corn." or something more specific.
