What are some of yours?
I've been physically assaulted by unknown entities twice in my life... once as a small child, two (what I can only describe as demons) things rushed through my bedroom door and tried to drag me off. I (ever the atheist even then, was so terrified, that I called out for help and actually received it. A transparent barrier materialized and they banged on it with their powerful fists until they pissed off very frustrated.
They remain the most hideous entities I've ever laid my eyes on.
And another time, 17 or so years later. I was meditating by myself in a vacant field near work one night, sitting in a chair on a concrete slab and instantly (eyes closed) could see 6 shadows surrounding me in a 180 degree semi circle.
I thought to myself, "I've got a cool imagination" as the closest one (about a metre away) raised it's silhouetted hand and slowly made towards my eye.
It was like being stabbed with a syringe. Tears pissed out, I grabbed my face, calmed myself down by rationalizing how it was probably an eyelash which poked me in my 20 minutes closed eye... and left, never to meditate again.
Although I've had plenty of good experiences. My grandparents visited me during a time of need and talked some wisdom into me. I have no doubts it was them.
I've seen statically located smoke spirals rising and felt presences in many a freezing room before.
Carried on a few conversations with a few wayward wandering spirit types.
The list is endless of what I see from week to week, year to year.
What are your experiences?
