The dream in which you are visiting the hospital warns about health issues that must be dealt with immediately, otherwise the consequences will be sad. If you see the other person being in the hospital, then such dream foretells about the help this person is required. If you see yourself being a worker of the hospital, but in your waking life you are not working there, then it means that you spend too much time solving other peoples problems or helping them in any other way.
