I just started meditating a week ago. Everything was going incredibly well and as time went on I began to feel increasingly happy and at peace.

However today when I meditated I was confronted by a horrible sense that someone was there. I did my best to ignore this and focus on my breathing but found this near impossible due to the feeling of someone holding and poking at my neck.

Still, I persisted with my meditation only to find that my arms and head were moving involuntarily. Don't get me wrong, if this had happened in any other way it would've fascinated me! But hard as it is to describe, there was a strong sense of, well to be quite honest something evil lurking about!

I feel ridiculous posting this and am interested in serious meditation. Is this just a normal trick of the mind experienced by new meditators? Any insights would be hugely appreciated!
