A guillotine is used to chop someone’s head off. Since the head is associated with control and with rationality, a dream about a guillotine can be associated with a fear of loss of control or with a fear of behaving irrationally.
If you dream that you are being guillotined or that you are about to be guillotined, you may be worried that your emotions are getting the best of you, and that you are not behaving in a rational matter.
You could be worried that you have lost self-control, and this has caused harm to yourself or to someone close to you.
If you are executed by means of a guillotine in your dream, your dreaming mind could be telling you that you need to reconcile your rational and emotional sides.
Being guillotined in a dream can represent being separated from an aspect of your personality or from someone that you love.
If you are guillotined in a dream, you may have experienced a trauma in real life.
