An alien landing was going to happen around where I live, and the US government decided the best way would be to drop a nuclear weapon on it when it landed, therefore incinerating me. I remember feeling terrified about the impending doom.
Dreams about aliens usually represent the unknown or unfamiliar aspects of your life. This dream could indicate that you feel overwhelmed or threatened by a new situation in your waking life. The nuclear weapon symbolizes a drastic and destructive solution to this situation.
You may fear that this solution will have extreme consequences and may cause irreparable harm. It is possible that you feel like you have no control over the outcome of this situation, which is causing you anxiety and fear.
This dream also suggests that you may feel helpless and powerless in the face of a threat, and you may need to empower yourself to take control of the situation. Overall, the dream is a reflection of your feeling of fear and helplessness in a difficult situation.
