To dream that some person is obligated to you, indicates your victory in front of your opponents. If you are obligated to somebody else, it means the opposite, you will have to humble in front of others that will cause much of the stress to you. The obligation is also interpreted as the symbol of trust. The dream only reminds you to remember, that if you promised something to someone, you have to keep that promise and do what you said you are going to do.
