wow that was weird

??? OK i am playing fallout 3 (not asking for help) and i had to get this seed. when i got it this gas spray and my guy pass out but then woke up. well then i try to get stuff would not let me so i am like OK. i keep on walking and found this bubble head. i pick it up and it said you are stupid. you fell for another trap. and then i found another one and each time i found one it got weirder and weirder
lol what do you have to say to this

Might be a glitch?

I don't remember that quest at all, where is it?

It's in the new addon Point Lookout, it's part of the main quest where you are asked to perform an initiation quest to join a cult. It'll make more sense later on.Also moved to the proper section, please take more care in the future.
