Populus tremula Keywords: Fears & worries of unknown origin Aspen is indicated for people who are seized by sudden fears or worries for no specific reason, and who may therefore be generally nervy and anxious. A typical need for Aspen is for waking in fear from a bad dream, even if the dream itself is forgotten. Aspen is helpful for young children experiencing nightmares and night terrors (see also Rock Rose). Aspen fears can occur during the day or night; an inexplicable anxiety or sense of foreboding may strike when alone, or suddenly in the company of friends and may be accompanied by trembling.
