Jan Neruda said this quote
“ The Kammerlicht: Explanations of the Impressions Left Upon Various and Sundry Natures by Dreams as Interpreted According to Tribe, and of the Numbers to be Staked in Lotteries in Conformity with the Meanings of Said Dreams .. says … there are eight ‘tribes’ of dreams and of the eight only the fifth is genuine. Tribe 8 are dreams emanating directly from evil spirits. Tribe 7 are dreams granted to the virtuous as direct revelations. Tribe 6 are dreams from roots planted in disease (fever and such). Tribe 5 are dreams that come to those who have taken no food before retiring and are of a healthy & tranquil disposition. ”
