If you have dreamed of throwing a key into the sea in a dream: You may experience difficulties in joint money matters, it is useful to take care of things that you can enjoy yourself. Throwing a key into the sea in a dream indicates that you will lose hope in life, especially in love affairs, and will fall into pessimism with the deterioration of your relationship. While going through hard times financially, it is the harbinger of being alone spiritually and having to struggle alone in life. We can say that the person will have trouble and have bad days.
