Almost everyone has experienced it at some point. You wake up thinking about someone. Their name pops into your head throughout the day. A song reminds you of them. A random place triggers a memory. Before you know it, they have occupied your thoughts for hours.
Many people assume that constantly thinking about someone automatically means they are in love. While that can sometimes be true, the reality is often much more complicated. The mind tends to focus on people who trigger strong emotions, unanswered questions, or unmet needs.
