DREAMS IN THE VITAL PLANE
Most people move most in the vital in sleep because it is the nearest to the physical and easiest to remain. One does enter the higher planes but either the transit there is brief or one does not remember. For in returning to the waking consciousness it is again through the lower vital and subtle physical that one passes and as these are the last dreams they are more easily remembered. The other dreams are remembered only if (1) they are strongly impressed on the recording consciousness, (2) one wakes immediately after one of them, (3) one has learned to be conscious in sleep, i.e. follows consciously the passage from plane to plane. Some train themselves to remember by remaining without moving when they wake and following back the thread of the dreams.
The depth of the sleep in your experience was intended to make you go deep inside and, as soon as you did so, you entered into the psychic and spiritual state which takes the figure of the beautiful maidan and the flow of white light and the coolness and peace. The staircase was a symbol of the ascent from this psychic and spiritual state into higher and higher levels of the spiritual consciousness where is the source of the light. The Mother's hand was the symbol of her presence and help which will draw you up and lead you to the top of the ladder.
Imagined scenes or great eternal worlds,
Dream-caught or sensed, they touch our hearts with their depths;
Happier than happiness, truer than things true
If dreams these were or captured images,
Dream's truth made false earth's vain realities.
