Radioactive – Dreaming of radiation and radioactive things indicates a fear of some invisible or unseen thing that will poison all of your undertakings and even threaten your very identity. This may be a person who is not what he or she seems, or it may be a thought or belief that is sabotaging you. If you dream about a radiation bomb shelter, this indicates a great feeling of threat and a desire to hide from the difficulties in your life. It may also indicate blocking out the poisonous influences in your life. Pay attention if there are symbols or people outside the shelter, as they may give you clues about the threats you need to protect yourself from in waking life as well.
