You have abilities to access to another realm or another dimension. Some of what you have experiences were from your past life whether you believe or not and the other were that you have encountered certain energy force.
One thing you can do is like yourself said to say mantra in your mind like “阿弥陀佛”. You can also visualize lights that are pure love that around you to protect yourself or use the lights to suck the energy you have encountered.
Not too worry about what you have seen. It is nothing to do with your personalities or the things you did in the past. The fact is that you have some psychic power witch is not bad thing.
