How would you feel if you fell asleep and woke back up and you was on a planet with aliens?

I would be, shocked ... ?

Explanation:

I really don't know, I would assume its just a dream to be honest. This is a really weird question

Definitely scared at first because I wouldn't know what to do or even where to go. I wouldn't know if they were gonna harm me or not but I guess even if they were nice I would try to get a back home or start a plan
