Hi Catherine, definitely yes, both my books so far written have themes. The first one, Cielo is around the themes of addiction and how it can either destroy or hold back a life. Both my MCs in this book are addicts, and as a result of this the story explores loss, trust, and ultimately the ability to hope and love. Added to that there are the character's own passions in life which help them through, as well as each other. I gave them each a massive obstacle, one had caused the death of his son and the other has been in prison. All of this is given the added bonus of two dysfunctional families, and a serial killer sibling to boot. The second one, Hunt for Delphi has loss and the steps people take in life to escape their past. Also big theme of loneliness and isolation of where they live. All of this is again wrapped around trust, love and the fear of dying. I've also gone to town on some unlikeable characters and the efforts people go to in oder to get what they want. Both of these books started with a setting, then the characters and their motives, so themes are deliberate from the start, though as I am writing it out (I don't plan too much from the start), others can emerge as I go. To answer your last question, yes, both of them reflect things and people I have experienced in life. I think that's almost inevitable.
