Spinning may bear a positive or negative significance, depending on the context and the details of the dream. If spinning is seen as an attempt to complete a full circle, then it is a positive dream symbol illustrating your attempt to achieve perfection. Those who have such dreams are ambitious individuals aiming high, willing to put all their efforts and resources into attaining their ideals.
On the other hand, spinning as dream image may be a metaphor for something that spins continually and makes you dizzy, confused, not firmly grounded into reality. From this point of view, spinning dreams may describe disorganized and disorderly individuals, who experience chaos in their waking lives because they lack a sense of discipline. You should learn to put things in your life into order and draw an accurate plan of the path of life you want to follow. If not, you will lead an 'off the rails' life and will achieve nothing.
