Magical work of negative beings in my room

[zedro]

Killing your physical presence / body might not be their actual objective, as you can be the their 'food source'.
Making you think that they could kill you, which induces / stimulate fear emotion as a response from you is their actual objective. When you're in fear, your vibration become low and it's perfect condition to 'consume' your low vibrational energy, which is their food.

To add, it may not even be fear (although it is probably the tastiest treat), but just your attention in general (which can be many modalities, referencing the different energy centers). It takes energy put into the contact to extract energy from you, so if you achieve and maintain a state of non reactiveness, it becomes a losing proposition as more energy is expended than is extracted from the attack (hence some depolarization).

Think of it like having a bully, they want you to fight, to react, to feel shame, to be scared. But once you are nonchalant to them, they have no more power over you, and their actions become foolish and counterproductive to their egos. Maybe they can see the error in their ways, but that is up to them, and whether you are part of their catalyst for change is a matter of destiny, I would not make it your mission. Love is your defense, how it affects your attacker is not up to you.
