He recorded his dreams since the age of thirteen. In his journals, he described experiences of dreams where he was aware he was dreaming, making his work the first recorded instance of lucid dreams. ''Memento Mori ''is a Latin phrase that translates as '''Remember Death''' or more commonly ''Remember you will die"''. It was popular during the eighteenth and ninteenth centuries for scholars and philosophers to have some form of imagery in their studies, typically near to where they worked, to serve as a reminder of mortality and the fragility of life. Such things were usually skulls or hourglasses made from various materials, bone being quite popular in Eastern countries.
