I think her mentioning of going into another dimension means entering something that can't be explained from this side of the veil. Beyond our conception of "space". Within that dimension, as seemed to have also been in Natan's NDE, you can understand things given to you of the future for a particular purpose....warning, etc. .... and understanding many things in what seems to be a very short time when explained only via earthly experience of time, etc. So you could be placed within a future situation but within a familiar setting and with the ability to notice changes that have happened to it. The visitations to Scrooge sorta took that into the arena of possibilities as when he viewed the possible future if he didn't change. Also Ned Dougherty spoke of seeing a future where the expected Era of the Divine Will/Era of Peace is seen to some extent and how during a period of transition up until that fullness intended, earth and man will gradually be changed.....like as we pray "send forth Your Spirit and we shall be re-created and Thou shalt renew the face of the earth". He is shown only up to 2034 but does see quite a change/evolution of nature and man in Christ....beyond that could be the completed change to this Era of "heaven on earth". Within this experience he was shown his old neighborhood, his grandmother's house which first appeared old and shabby but then he suddenly saw a change into this future of new light and "energy" flowing through everything probably like the original garden had been with the preternatural gifts that existed for man then and intended to continue before the original sin....and which also fits with living in the Divine Will where praising God within the Divine Will can contain all of the cosmos etc. .... as in Luisa Piccarreta's writings. There are studies already that attempt to take into consideration the effect of negativity of spirit/which sin has contained from the beginning.....as in curse words, inward hatred towards others, the horrible sounds that come for instance with the "heavy metal" sounds vs the effects upon creation of kindness, loving intentions from the heart, the unity of sounds within, say, Mozart's compositions (monks have noticed that when they play Mozart around their cows, they give more milk, sweeter tasting, etc.) and such effects have been shown on water crystals....because God is unity and His creation, as intended, in meant for such connection and unity. Difficult to express exactly but now already experiments are literally being done that prove in their outcomes the facts built into creation when it comes to positive vs negative approaches. I think we are going to see and experience some very remarkable changes....even within the possible earthly disasters that is necessary to make these conditions of the New Era complete and ourselves worthy of that Era!!
