I just had a dream with Trump, dead serious. That he came here and his black suit jacket was too big for him and just weird pants on. I said your suit

It sounds like a metaphor. Trump was a businessman who became president. It’s a huge difference. The size of his suit in your dream could be the position he has now. It’s not the one that would normally fit him but he says it does. It shows that just because you don’t seem like the right person for the job doesn’t mean you are unable to do it. You simply have to put on the suit and tell those who say it doesn’t fit you that they are wrong.
