It might seem ironic to call a disabled person strong but at the same time it is ableist discourse to think that a disabled person cannot also be strong in many ways that a perfectly able person is not. In any case, a dream of a disabled person is usually not an ordinary one, making it quite a special dream experience.
If you have a dream about a disabled person and you are that disabled person then it means that you feel like you have failed to do something and this is making you self conscious. Because of this previous failure or because of the fear that you will fail you start to feel useless as if you cannot perform to the level that is expected of you. If you want to do well you are going to have to suck it up and go with the flow, it’s the only way to make sure that you do well.
Being disabled comes with a sense of frustration whether a person wants to admit it or not. Even the most able bodied people that are still technically considered disabled will at some point feel frustration about how difficult it is to cope with the world around them that was clearly built for people that were more able than they. If you have a dream about being a disabled person then this probably means that you are feeling like you should be frustrated about something that is going on in your life which is difficult to deal with. If this sounds like it is the case for you then this may be why you are having this dream.
