Hi Kiya, mostly in my case they are seen in dreams or thoughts but in some cases I have seen them revealed (halucinations), I have tried to communicate with them but they dont ever move thier mouths (except once) and when I make a effort to communicate, through my thoughts, they just disappear

I did have a very wierd experiance (recently) where one actually spoke words though ..... and said " Do you see me " I am a little leary to share this here though, and that is all that was said anyway
