The dream interpreter are human, and as human they are not free from mistake. So do not take what the dream interpreter say as the truth that definitely will be happen.
Okay bro, suppose, you tell your dream to a sheikh, then sheikh say "This dream meant, your spouse will come from east direction". If you just take what sheikh say as possibility that could be happen, it's okay. But if you believe that what sheikh say definitely would be happen, sorry, it's shirk.
So, although dream interpretation is allowed, we should not believe dream interpretation as truth that definitely will be happen. Like I have said, no one know what will happen in the future.
