To dream of lending to others represents your support for others or to a cause. Helping others with ideas. Lending may also reflect doing someone a favor or your trust in others returning a favor. Trusting others to be responsible.
Negatively, lending to others may reflect enabling dependency. It may also reflect too much or help or trust being given to people who may not deserve it. Feeling that others are not appreciating your help or using you. Doing people favors because it will allow you to exploit them or get something for yourself later.
