This could mean one of two things.
1) You are afraid of something precious to you being taken away.
2) Something you have worked on is not going according to plan.
Who is being abducted? You? Someone you love? Someone you don’t know? Everyone else in your dream… even the “bad guys” represent a characteristic of yourself. For instance your mother in the dream represents your motherly or nurturing instincts, even if you are male in real life. A villain in your dream physically symbolizes your shadow self.
If you are being abducted, what from? Home? Your normal life? Those are the things you fear you’ll lose in real life.
Remember, this is just a fear. In reality you are actually safe and your subconscious knows it. It's only trying to scare you into taking proactive steps to empower your confidence. Reduce your real life fears in order keep this kind of dream from reoccurring. Easier said than done.
