This dream may symbolize a warning about a potential danger in your waking life. The person you are talking to in real life may represent someone you trust, but the fact that they got a hotel room and wanted to put child locks on the windows could suggest that they have ulterior motives or may not have your best interests at heart. The person calling on the phone could represent your intuition or a warning from someone else about this person’s true nature. The fact that they had a knife in the past could symbolize their potential to harm you emotionally or physically. Your friend’s presence and suggestion to leave with her could represent a desire for safety and protection. The ambulance and police at the end could symbolize the consequences of staying in a potentially dangerous situation. This dream may be urging you to trust your instincts and be cautious of those who may not have your best interests in mind.
