I was wondering if spirit guides ever show themselves? Reason I ask is, few years ago something strange happened and I wasn't sure what it was, until I asked someone and they said chances are it was my spirit guide.
But, I thought spirit guides were 'nice'?
I'd lay down ready for sleep, and had been experiencing a lot of activity in the home. Just as I closed my eyes, this 'head' came right up close to my face, seemed to just zoom in quickly

I jumped and told it to eff off

and it seemed to fly backwards at an amazing speed...until it disappeared.
I can still remember it vividly. It was greyish/purple in colour but looked real sad. No smiles, no expression. Just a head, no body attached
I never saw it again after I told it where to go lol. But someone said that could have been my spirit guide. Are they that miserable and can we see them?
