How do you ask the guy of your dream out?

Yes, why wouldn't you?

You cant, you've gotta make the first move.

This is a wish-fulfillment dream. It illustrates the desires of the dreamer. It does not reveal any of the guy's actual thoughts or feelings.

well maybe just ask him if he is gay then if he isn't then you should just joke around and stuff and find somebody else.

you ask a friend to ask them if they like you if they think about it and then last second say no they like you. Later one or that moment you go up to them and ask them out if they say no say alright...
