Pulling suggests a positive action. We are being alerted to the fact that we can do something about a situation.
In dreams, if we are pulling we are making the decisions within a project.
If we are being pulled we may feel that we have to give in to outside pressures. Extra effort to have something happen may be necessary.
The object we are pulling, and the means by which we are pulling it, may be important.
For examples, see bridle, rope etc.
