Dreams of being chased often reflect feelings of anxiety, fear, or avoidance in waking life. The shadowy figure dragging his leg may symbolize an issue or emotion that you find difficult to escape from, even if it feels slow-moving. The repetition of the word "one" could suggest a sense of being targeted or isolated, perhaps indicating a struggle with a particular situation or feeling that you can't shake off.
The sensation of someone laying on top of you and whispering in your ear adds a layer of intensity to your experience. This could represent a feeling of being overwhelmed or pressured in your waking life, as if you're being burdened by something that's hard to ignore. The fact that this happened three times might signify that this issue is persistent and requires your attention.
Consider reflecting on any current stressors or unresolved issues in your life that might be causing this sense of pursuit. It may be beneficial to confront these feelings directly, whether through journaling, talking to someone, or finding healthy coping mechanisms. Pay attention to what "one" represents for you; it might be a clue to understanding the root of your anxiety.
