Looking at the names of current bands, it seems as if some of them do have a lot of depth to them - while others are very random.
I think SydFletcher is right - inspiration IS all around you. I would suggest taking a day to just take in your surroundings, pay attention to what grabs your attention, and jot down as many ideas as you can.
Another option is to think back to your childhood. Is there a particular story or memory that comes to mind? Something that may sound abstract to someone else could have a lot of meaning for you, and might be a fun and creative way to find the right name.
