To dream that you are ordering or eating takeout food implies that you are looking for some sort of emotional support. You are not spending enough time confronting your feelings or you have avoided your feelings for too long.
Alternatively, the dream may be a metaphor that there is something that you need to “take out” or “take away” from your life.
To dream that you are dressed as a Chinese takeout container means that you are lacking some sort of social life. Perhaps you want someone to take you out.
