I used to have several recurring nightmares. They weren't really terror inducing, just negative with maybe a little panic involved. The one involving a person I knew always involved a scenario where I needed to call my then SO and no matter how many times I tried to dial my home phone number I would get it wrong. The meaning was alway obvious to me, it symbolized my lack of feeling of connection to my now ex.
I find that dreams always have meanings to be taken from them. Tht doesn't mean that I necessarily think that your subconscious is trying to tell you something in them. It is trying to build a narrative and will grab at the most convenient symbols depending on the scenarios and other symbols involved. The associations in my dreams are usually very revealing.
