You feel your body being lifted up off the muddied ground, your whole body just floating upwards as if the air had become like water, lifting you to the surface, and that surface was something unearthly. Above you, trails of hovering lights danced in the night sky, like fireflies going in circles. In the center was a bright white light, pulling you towards itself.
It was a spaceship, and you were going inside it without a shadow of a doubt.
The bright light ensured that you were safe but unable to escape, rendering you as powerless if you even dared to escape or try and find a way back down. You arrived in the ship, the doors closed, leaving you in the hands (or god knows what) of whoever or whatever was controlling this insane vehicle. Your eyes were adjusting, trying to see anything or anyone after the bright light took you from the ground below.
This was your first experience ever encountering aliens.
And this will be your last experience ever being human ever again.
The beings on board this vessel will alter you completely. Once in, you will never be able to resist the changes that they have set out for you (and anyone else they find). Your body will change, your memories rewritten, your personality altered beyond fixing, and your own goals will become what these creatures want it to be. You will be like these creatures. You will become them.
The question is: What do these creatures look like? What will your future form become?
