Being disorganized is not the same thing as being messy and it can be better or worse depending on how you look at it. If your room is just a bit disorganized and things aren’t in the place that they probably should be this is certainly better than having a room that looks like a tornado hit it. However if your room is so disorganized that you can’t find essential things when you need them, this is not a good thing.
If you have a dream in which you see things around you are disorganized or out of the order that they are normally in then this means that you yourself feel very disorganized. If you are normally the type of person that likes to keep everything in order and ready to go at all times then this means that you have a lot of worrying to do and a lot of work to deal with. What this kind of dream means about the real world is that you feel disorganized in real life. You may have been disorganized for a very long time, but this is the first time where you can actually feel it. The debilitating effects of being so disorganized are palpable here and it is holding you back from what you want to do in reality.
If you are normally disorganized like this then a dream like this can just be a reflection of your everyday life, but if you are not disorganized normally then this kind of dream can mean that you need to put your life in order.
