I would like to dream about my ex-girlfriend who moved somewhere else and it is hard. I think about her and I do have her in my dream sometimes but it is hard to become lucid. It's like she is in my dream but I am unable to kiss her or do what I want because there are other stuff going on like I could be hanging out with some friends, and I think this is because I am not aware that it is just a dream. Can someone give me any advice or technique on how I can fix this problem?
