Wheelchair
To dream of a wheelchair is a symbol of a handicap, though not necessarily a physical one. It is an indication that you have been relying on the assistance of others instead of handling your problems yourself. You may feel that you cannot control some aspect of your waking life. Conversely, it may mean that you are letting the people in your life take advantage of you or 'push you around.' You must not allow anyone, no matter how close, to use you.
If you dream that a friend or family member, able-bodied in your waking life, is using a wheelchair, this should be seen as a call to action. They are in desperate need of your help but cannot bring themselves to ask you outright. Instead your subconscious mind has picked up on subtle hints. Seek them out and offer your friendship and your help.
Affliction

To dream that an affliction affects others, you will be enveloped by bad fortune and possible anguish.
