People that are rising in frequency can literally be known as "ghost-like" or unreachable because that are on a plane of frequency/sight, that is so fast that one would need to become like them to resonate with knowing their existence, Like attracts like. Their are beings that exist in the 4th dimension that are benevolent and some that are malevolent, the good thing is, the continuation of your meditations, visualizations, and studies of a higher nature (as well as fasting/not eating or drinking for a period of time) will help you to resonate with higher benevolent 4th dimensional beings in mentally directing your thought energy towards benign or benevolent thoughts that different degrees of the 4th dimension resonate with.
