Questions for the spiritually inclined

I lived in a house 70/80's that had spirits. At the time never thought to try to communicate. Ghost hunters changed that later in life.
One week end my parents were out of town, i invited my GF and another couple over to watch movies and have pizza. They swore up and down they say my father walk in the house..took them on a tour and repeated all night long....its just us. They saw some one walking around the house when no one else was home. I had seen it myself at other times and it would freak me out. So had fun letting the spirits play with them.

Spirits are simply us without a body. There’s no need to get overly excited about encountering them. With some discipline, proper guidance, and by sharpening your inner senses, you can naturally experience these souls. Depending on their nature, souls exist in different realms. As they attain a certain level of ‘calibration,’ they become ready to take birth and evolve further. The realms they reach are what we often recognize and name as deities, angels, demons, and so on.
