This dream may symbolize feelings of invasion or intrusion in your personal space. The fact that you are still in a dream state suggests that these feelings may be subconscious or repressed. The hallway light being on and your room entrance being open could represent a sense of vulnerability or exposure. Your brother’s presence and attempts to communicate with you while you are trying to sleep may represent a lack of boundaries or respect for your personal needs. Your inability to yell or punch him could indicate a sense of powerlessness or frustration in dealing with this situation. The ominous feeling and your brother hovering over you could symbolize a sense of fear or intimidation. This dream may be reflecting a real-life situation where you feel your personal boundaries are being violated or disregarded. It could also suggest unresolved issues or conflicts with your brother that need to be addressed. Consider exploring your feelings and setting clear boundaries in your waking life to address these issues.
