I think you had an insightful self-reflection, Sheeppilled!
Please don't think i am discrediting your experience, for I wish to share some objective tools to help you develop it!
Have you felt anything like this with characters before?
Can you say you identify with this character, or have formed an emotional attachment to their form or personality?
Are you going through changes in your life (through growth, emotion, environment) that might create an impulse towards this character that you might not have otherwise?
What do you think is the most simple explanation you can think of to explain your deep feelings?
These questions may be fairly private and it may be impossible to fully answer them in the short term, I understand!
If you feel a strong fiction-kin element then looking within like this from time ot time may help you bridge a stronger bond with this new aspect of yourself. Maybe write some fan stories that involve the character, even as yourself and explore!
