I experience this weird sensation with very specific smells.
Some things remind me of being a kid - and how things smelled.
Or when I first smelled something new, somewhere new. Or meeting someone.
Even smells that remind me what being in love really did feel like.
Or that time when you smelled it and couldn't remember it, but just that you loved the smell.

Noses, barging into other things. Taste receptors allowing for the particles of whatever = invade space.

I thought about what life would be like if I indulged in the things this world tells me to: it looks so empty and unflattering. So wasteful and withering. It looks opulent, lavish and elegant at first - but it ends in death. I'm learning more than I thought I would. So much to take to heart. God is showing me a hard line, and it's wonderful to have some clarity for once - to make sense of.
