Hello, I am new here.

I have an important question regarding the power of mirrors and blood.

I know that mirrors might be portals for interdimensional entities but I am not sure. If so, I know also that blood has a great impact in the magic world.

But let`s say that some people that have pimples on their faces might drop accidentally drops of blood on the mirrors when they squeeze the pimple.

If so, would that mean that a person is more vulnerable to an entity attack ? or it has no power at all if there was no intent ?

Or is the belief that gives power to such things ? Only if the person believes that an entity can influence that person by doing such things, the entity can influence that person ?

Please tell me a honest oppinion on my question.

I really want to find the answer guys
