what does this dream mean?

Just means that the 11th salesman forgot his human suit.

Let me interpret this dream

10 = perfect number

real estate office = place to sell/buy houses

beast looking thing = monster or adult

Young men = should still be in school.

If I am not mistaken, your dream is a about some kids are making troubles afterward. That extends the picture as follows. The ten young men went into the real estate office and trying to buy/sell houses or mess around and turn out the "beast" or the adult kicked them out.

If you are an adult, you probably have issues with kids. You don't want them to be around, especially teenagers, they may invade your privacy which in this case you project yourself as the beast to show the young men off which they are not welcome in your terrority.

If you are one of the young men, which shows your rebellion against older people. You make youself 10 of them, but you still get kicked out.

Either or, it is about relationship between teenagers and older people. The dream implies some deep meaning which may indiciates non-communication between those two groups.

I could be wrong, but that is how I see from your dream.

the ten men were homeless people, and the beast was the overpriced real estate market. The dream means that the prices are soo inflated, that sooner than later 10 men won't be able to afford to buy a house together so the RE business will eventually fall out.

I have no idea what it means.

I need more that that! Were they scared of the beast. Did the beast have certain characteristics. I'm really good at this, if you can give me more info. Also, how did you feel watching it happen?

dont buy any real estate inthe near future coz the beast u saw was bad luk!

maybe you are entering into a bad real estate deal.

Maybe you need to get one of those dream analizing books. They have them in almost any big book store

it probably means maybe if your trying to get a house or thinking of it your scared you might get screwed over
