Dream about dead owl signals hard work. You are trying to sabotage your relationship in some way. Someone is not who you thought they were. Your dream states someone who is loony or crazy. You need to be steadfast and not let others questions your authority and position on things.
Dead owl dream states a loss to your individuality. You feel empty inside and need to be fulfilled. You are not fully acknowledging your own self worth. It is bitterness, jealousy, or rivalry in your family, depending on your relationship with your family. You need to simplify your life and get back to the bare basics.
If you dreamt about dead owl:
Repeating the same old patterns and ways of relating is not going to improve your current relationship; it will just stay pretty much the same, except that part of you will begin to feel cramped and limited.
