Becoming a non-human creature

I often imagine what it would be like to become a non-human creature.

If I were a sea creature, I wonder how I would perceive the land.
Would I think of it as a terrifying place where I couldn't breathe, where harmful ultraviolet rays pour down, and where my body would quickly dry out?
I might find a life where vertical movement is difficult and where one is kept pinned to the ground by gravity to be truly miserable and restrictive.
On the other hand, I suspect it would be difficult for a sea creature, unable to look directly at the starry sky, to imagine that there is an unimaginably vast universe beyond that terrifying space.

I also often try becoming an alien.
For example, if I were an alien from a planet without clouds, I wonder how amazed they would be at the sight of numerous massive objects floating in the sky, changing shape as they drift.
How would they feel about liquid or liquid crystals falling from them, or the way they change color to white, red, or black?
However, since the colors they see might be completely different from ours, they might only find it eerie and frightening.

I imagine what it would be like to be an insect that is born in spring, lays eggs, and dies in autumn.
They never meet their parents or their children.
I wonder what life is like for them, as they have no opportunity to witness the chain of their own existence.
They might not be able to possess the sense that the world continues after they die.

As I imagine these various things, I realize that what we think of as the world, or life, is actually just a very narrow perspective from our current position as humans on Earth.
