Because you are a multi-dimensional being, you exist eternally on ALL dimensions, NOW. Each dimension is simply your perceptual awareness. There are people existing (perceiving) on ALL dimensions here and now on Mother Earth. In order to stay in a higher dimensional awareness, your vibration must remain high enough to sustain.
In the 3rd dimension, you do not perceive your higher aspects. You are asleep, so to speak. Source is believed to be outside of self, and you see yourself as being separated from creation. You perceive good/bad, right/wrong, black/white, all in duality. Fear resides and dominates in 3D. Your lower nature, or ego, is your driving force. Time exists and is linear.
The 4th dimension is somewhat of a “bridge” between the lower density of the 3rd dimension and the higher realms. You are still anchored in 3D fear and ego, but there is an awareness of the 5th dimension. You cannot fully dwell in the 5th dimension without transcending the ego and letting go of fear. Space and time exist in 4D.
In the 5th dimension and beyond, I am limitless. I AM aware of my divine connection to ALL. I AM conscious creator of all I experience. I am aware that I exist multi-dimensionally. I have NO FEAR! Fear is only an illusion. I LOVE ALL UNconditionally. I transcend space and time. There is no past or future, only NOW. I AM connected to the universe. I AM the universe, for it dwells within me. Everything is divine. There are no coincidences, only synchronicities. I am connected to my higher aspects of self and directly communicate with the heavens. ALL is beauty and LIGHT! ALL is LOVE!! I AM experiencing the kingdom of heaven that lies within.
