Dreaming about school as an adult is usually attached to feelings of inadequacy that are associated with school. Dream interpretations regarding school are usually negative because as adults we tend to look back on our school lives and emphasize the more negative aspects of it. As a dream symbol, school may have negative associations even for people that enjoyed the majority of their time in school. But it is inevitable that eventually the negative aspects of you time spent in school will creep back into your memories. Even a dream that is mostly positive involving school is usually indicative of you revisiting a negative time in your life that happened at school while you were awake. This is why the meaning of dream involving school can often be difficult to determine.
Other dream meanings attempting to define dreams about school state that it could be a symbol for lessons that are being learned. If you have learned something important in life, or several important things, your subconscious may be providing a school setting to let you know how much learning you've really gone through. Alternatively, if you are young and still currently attending school, then a dream about school may not have a dream meaning at all. Conventional dream interpretations usually rely on unconventional settings or visions, seeing something so familiar to you may just mean that your mind is putting you in a familiar setting. This means that a dream about school when you are young won't necessarily have any really important significance when trying to find a dream interpretation.
Looking through a dream dictionary, you might come across a definition for school which shows a definition for what happens when you are looking for a school. The school that you decide on in the dream isn't actually important. What is important in this dream is the fact that you are searching at all. This indicates a desire to learn and to expand your knowledge. When you find yourself looking for a school, this means that you desire knowledge and shows a remarkable character.
Sometimes you might dream that your childhood school has been destroyed, or that when you look at the school that you want to as a child, it has been destroyed. What this indicates is that you are thinking about an issue that you haven't been able to resolve for some reason. This would be an issue that you've had since childhood. It doesn't have to be something that is associated with your school experience directly but it is often likely that it is something related to your school. It could also mean that you are too fixated on the past. Look to the future and stop focusing on past events that can't be changed. This is the best advice to give if you have been having dreams about your destroyed childhood school.
