Oh that is wild, so completely different.
If I'm home alone, I always put some music on. Not loud, as background. Without it feels uncomfortable. Too quiet.
As for picturing an apple, if I close my eyes, I can see the apple, with it's shades of color. I can see how it looks in sunlight with a shadow, or illuminated by a flashlight in a dark room. I can pick it up, rotate it, pull the stem out bu twisting it and take an imaginary bite. However, I can't really put thoughts into the taste or smell though, other than the basic sweet/sour. I can imagine the texture of the bite, somewhat.
