you are working as a janitor at this military facility/camp. One night you were cleaning in the main room when you overhear some personnel talking about a unknown alien signal but saying it's nothing to do with aliens.

you later sneak into the room and listen to the strange signal. You were always deeply interested in space and otherworldly aliens so you decided to record your own message and send it, but in doing so the facility powers down when your message is sent. The next day you were fired for doing that.

night cane and you were walking along a beach when you saw strange lights coming from the water. Suddenly, time freezes and a UFO opens up and beams you into a portal. You appear floating in a white room before the artificial gravity turns on and you fall.

a strange floating blob then appears next to you and starts speaking.

OOOOO: greetings new species, I am OOOOO. Your guide to help you get settled in. starts scanning your body and how it functions.

a floating platform appears below you and takes you to the central room of the ship, multiple other aliens then come towards you on their own floating platforms.

OOOOO: greetings ambassadors.

Helix: so this is the new one. Absolutely ecstatic to make your acquaintance.

Questa: certainly. Let me take a look. One cerebellum, four lobes and gasp a medulla! May I? tries to touch your forehead with her antennae to read your mind.

Tegmen: now now, no need to overwhelm them.

this is going to be a wild ride for you.
