Dream about amputated thumb means the sun. You need to live up to the vows and promises you have made. You feel the rules do not apply to you. The dream signifies your fear or dissatisfaction of the future. You need to be more mature about some situation.
Amputated thumb dream is your need to connect with others on a mental level. You are putting up a barrier between your conscious and subconscious state. Perhaps there is a girl that you like and you are not sure if you should pursue her. This draws attention to your fear over something you heard. You need to protect your ideas.
If you dreamt about amputated thumb:
You feel the pressure of having to produce something without the resources needed to do so. Others are demanding that something be done, but the lack of foresight on someone else's part is making this task impossible. Do your best with what you have.
