2 ASPEN (SECURITY) 20 ML BACH
It is the flower for vague, unknown, and seemingly causeless fears. On one hand, Aspen's fear can be just a premonition, a disturbing anxiety that something unpleasant or terrifying is going to happen, and on the other hand, it can become a real terror with physical symptoms, such as goosebumps. In this case, Rock Rose could also be useful.
People sometimes think of Aspen as a fear that is only felt at night, as the sensations of unfounded fear seem strange. And of course, if you were in a dark room feeling afraid of something, but not knowing what, then Aspen would be the remedy to take. But when you actually fear the darkness, the remedy advised by Dr. Bach would be Mimulus since the cause of fear (darkness) can be named, while the nameless or causeless fears of Aspen can occur equally in broad daylight or at night.
