I was invited to work in a hotel. I tried to explain that i don't work there any more. Than there was something about having to look out for a man in opal shirt. I saw him fall down, drunk. I helped him up and asked where he was going? Than i went upstairs in the dining area and there was a table of Asians seating there with a man in opal shirt. they asked me if i would obey them. I agreed. Than i went outside with one of them and saw a bunch of demons rushing out of the ocean. I looked back and saw them going after my friend and i started fighting, and woke up that moment.
it was kinda like that image, but in new yourk and a bunch of differenk kinds of demons

Lots going on in this dream. Knowing the meaning of the symbols should help you figure it out:

hotel (unless you used to work in one, in which case, it may be an allusion to a work situation): dreamdoctor.com/dream-dictionary/definitions/hotel.html
foreigner: dreamdoctor.com/dream-dictionary/definitions/foreigner.html
demon: dreamdoctor.com/dream-dictionary/definitions/demon.html OR...
monster: dreamdoctor.com/dream-dictionary/definitions/monster.html
ocean: dreamdoctor.com/dream-dictionary/definitions/ocean.html
fighting: dreamdoctor.com/dream-dictionary/definitions/fighting.html

Dream are expressions of your feelings about your waking life at the time of the dream. Without knowing what was going on in your life at the time of the dream, it's hard to be specific. Based on the symbols, it would seem to be about your work or professional life... given the references to work, taking orders, and the NY setting. There are demanding foreigners, out-of-control (drunk) people and then a lot of demons/monsters, who could represent anything from a mean boss to difficult customers. Your friend in the dream provides an additional clue. Is he/she someone you work with? Is your work life (or your friend's) wreaking havoc on your friendships? Is this about a job that you left and your friend is still there dealing with the demons?

Because feelings in dreams are never disguised, try to identify where in your waking life you feel as you did in the dream. That will help expose the area of your life that your dream was about.

If that doesn't help, please share what was going on in your life at the time you had the dream. Thanks.
