Dreams are kind of a random assortment of things that have entered our subconscious and could have a variety of meanings but a possibility I would consider is that you have a subconscious feeling that you are repeatedly developing attachments that are quickly lost.
every dream has no meaning that is all your mind but sometimes it can has a meaning
It means that you are growing mentally. Because dreams are all related to the mind. Your mind might be growing.
Fear of growing old, or a bad relationship
It means you had a dream. That is all
To dream that you are pregnant symbolizes an aspect of yourself or some aspect of your personal life that is growing and developing. You may not be ready to talk about it or act on it. Being pregnant in your dream may also represent the birth of a new idea, direction, project or goal.
that you are horny.
you're squished.
you're thinking of being an actor/actress
Probably that you have an emotional and irrational fear of hair growing on your body.
It's just a dream so it doesn't really mean anything.
Dreams reflect a person's concerns, they are not mystical portents of the future. If you dream about your boyfriend's son being mean, you probably are a bit worried that your boyfriend's son may turn out to be mean.
The dream expresses the dreamer's feeling of not belonging or not fitting in with family or peers.
