The white splashes migth just be your astral vision improving, it migth be some form of energy that you can only randomly see because you can't be fully aware of your astral vision yet. Practice a little bit more, about the fear thing, it hapened to me too, my grandma was a vident, i was very afraid of spirits etc... when i started getting interested by it and getting some experiences i could feel somethings around me, and I started loosing the fear. Just practice. ='D
