ANSWER:

It is permissible to say good dreams to people who care for you. It is prohibited to tell about bad dreams to anyone.

Whilst growing up I have always been told when I have a dream, I cannot mention it because it is disliked and bad to do so. I understand there are dream interpreters you can talk to. However, if I wanted to mention my dream to a trusted friend or a family member, is that bad?

In one of your videos you said that some scholars have said that if a person describes his bad dream to anyone, it will come true. My question is, if Mr A dreams a bad dream about Mr B, such as bad things are happening to Mr B and describes the bad dream to Mr C, will this bad dream affect Mr B? But here Mr B doesn’t do anything wrong.
