It is difficult to communicate such things as we are attempting in this thread in our linear language, we don't have the correct vocabulary, because of this, we are forced to use words that have religious connotation. I think demons is a proper term for the most part, for the type of encounter Astral Explorer spoke about, but people that aren't affiliated with any religion reject what is being proposed because of how it sounds.
The essences of dead family members visit with me in 'dream' time, they have vibration signature that I am now familiar with. But can malicious entities visit and pretend to be something they are not? Absolutely. They do all the time, depending what realm we happen to be in, what our frequency is at the time, and by far the most important, what our genetics happen to be.
