I still have dreams about my ex, sometimes they're good and sometimes they're bad. What does that mean?

That means that your ex as well as your relationship is still on your mind. Like most relationships, they're not all bad nor all good. As such, your dreams reflect both bad memories or happy moments, as well as things you have considered regarding those thoughts. Your dreams are merely a reflection of what you are thinking about and may provide some insight into what you should spend more consideration on.

Maybe you have not completely let go off your ex yet. Is there something that hasn't been finished between you both?

I think a lot of people go through this. We all dream about people we care for it’s only natural, it doesn’t necessarily mean anything

It means you are too lonely. Get your mind occupied. Get somebody or something else to occupy your mind with.

Well, dreams are basically lucid thoughts, and are often influenced by what you were thinking before you went to sleep. So depending on whether or not you were feeling happy or upset with your ex when you went to sleep can have a huge effect on your dreams. It doesn’t necessarily have a meaning, and it’s perfectly normal to have mixed feelings about your ex.

You cared for this person a lot at a time in your life. There will always be a part of you that is connected, but that doesn't mean that you were meant to be together.

It's normal to have dreams about your ex. Whether they're good or bad, dreams reflect what you've thought about or what sticks in your head. You may be stressed about it, or perhaps some positive feelings are still in your mind. I do believe they fade over time, but I wouldn't ascribe specific meaning to them.

That could mean that you are still attached..depending on th end of the relationship and the way it ended could change how things effect you.

It means that you still think about them, they were once a big part of your life, as you were theirs. Memories don't disappear.

Your ex had always space from your memory. Your memories with that person will never be forget especially if it involves intense emotions. If you dream about your ex it might be possible that your subconscious mind has unfinished business that needs to be settle. It's either questions, doubts or 'what ifs'. If it is good dreams, it might be possible that you treasured your memories with your ex and your subsconscious mind reminding you "hey that feels so good to be with someone whom treats you special"
