Dreams about old bygone things come up from the subconscient which retains the old impressions andthe seeds of the old movements and habits long after the waking consciousness has dropped them. Abandoned by the waking consciousness, they still come up in dreams; for in sleep the outer physical consciousness goes down into the subconscient or towards it and many dreams come from there.
When one is in the physical consciousness, then the sleep is apt to be of the subconscious kind, often heavy and unrefreshing, the dreams also of the subconscious kind, incoherent and meaningless or if there is a meaning and dream symbols are so confused and obscure that it is not possible to follow it. It is by bringing the Mother's Light into the subconscient that this can be dispelled and the sleep becomes restful or luminous and conscious.
As for the mood that came on you, it comes up from the subconscient, where things of the old nature sink when they are rejected. When moods come up like that, you have to remain quiet and call the Mother till it is gone. After a time this power of mechanical repetition without reason from the subconscient gets worn out and disappears -- then these moods come no more.
Into the abysmal secrecy he came
Where darkness peers from her mattress, grey and nude,
And stood on the last locked subconscient's floor
Where Being slept unconscious of its thoughts
And built the world not knowing what it built.
There waiting its hour the future lay unknown,
There is the record of the vanished stars.
There is the slumber of the cosmic Will
He saw the secret key of Nature's change.
