It's a pleasure to read you and to share the experience of your dream. It revolves around your mother and this friend. These are particular symbolism in dreams. In your specific case, here is what we need to understand.
Dreaming about your dead mother carries a relevant message. In the case where you lead an impulsive and somewhat reckless life, it is a great warning to come to your senses.
It will mean that your mother, from where she is, feels uncomfortable that she cannot guide you on the right path.
The attitude to adopt here is to pray that your mother can regain her serenity. At the same time, you will be able to live better with your small mistakes, while learning.
It is your own experience and she is no longer there to accompany you. So please include this intention in your wishes for her.
If, on the other hand, you had a very close relationship with your mother, this appearance in the dream can be interpreted as a sign that she still supports you. She feels fulfilled by the idea of the life you lead and shows you her support through the dream.
If it comes to the boy following you, it is a clear sign that you are currently experiencing difficulties in your life. You are trying to run away from them, to escape the responsibilities and obligations they entail.
This situation reminds you that running away has never been the right solution, because the problems will follow you. Instead, you must face them.
Anessa, once you take time and step back to look for solutions, they will come to you. With wisdom, you'll get through it.
