This is nothing surprising, the kilesa (defilements) in your soul do not want you to improve your meditation as they actively try to prevent you from gaining more concentration, mindfulness. When you are meditating they will attempt to fool you constantly, it may come in the form of a horrible feeling, thoughts, visions.

Why do you think meditation is so difficult to master, why do you think there are so few who attempt it. The defilements in our own heart are actively working against us from attaining liberation.

When the disturbances come just observe them and watch them as they arise and fall away. The greatest warrior on earth is the one who can conquer himself.

This was very much out of the ordinary. Did you notice any unusual disturbances since then?

I wouldn't get caught up on the demonic experiences and I wouldn't be too focused on it, you have to understand that that happened after an incredibly intense effort and exertion on my part. I was living in seclusion following the 227 rules of a monk and fasted for 7 days. Literally every waking hour was spent in walking and sitting meditation as my master said I had to fully exert myself at that time for some reason. The event was extremely rare and I have never been attacked since. I wouldn't become too preoccupied on it, I more tell that story for aetheists you are still stuck in the idea that there is only the material realm and also to motivate people to work on themselves.

Are you still in contact with your guru?
