My current reincarnation thoughts

 Try to think of this as beautiful rather than gross. For example lets say you die and are buried into the ground. You will start to decompose and you get eaten by lets say a worm. You will become part of this worm because the worm is taking your matter allowing the worm to grow and produce energy.  You have now become part of this worm and every other thing that has eaten you. The left overs of your body will eventually break down and become part of the dirt where your nutrients will be eaten by plants that also become you. 

There are many directions you could go, following the plant path the plant could be eaten by a deer and then you would become part of the deer. Following the worm path the worm could shit you out leading you back to the plant path. Or the worm itself could be eaten by a bird and you would become part of the bird. Lets say the bird is pregnant with eggs, you would become the eggs as well. The bird uses part of you to create her eggs that will be laid, hatched, and become new birds. 

It is an endless cycle constantly mixing you up, spitting you out, and spreading you all over the place. You yourself are made up of many different things, probably even that butterfingers your mother ate and the ones you now crave yourself. There are many different endless paths you could take. You might be wondering what would happen if you were to be bitten by a dog or something (while you are still alive) and they happened to eat a little piece of you. Then you would just become part of the dog, simple as that. 

I hope this makes sense i haven't written in sooooooooo so long thank you for reading. If you think differently, see a flaw or something i missed I'd like to hear it just be respectful.
