'Also spiritual causes are possible... entity attachments or burnt out chakras. Psychic attack or curses. Even latent astral travel. Do you have vivid dreams? I know of people that are very tired cos they spend most of the night astral travelling instead of sleeping. Does any of that resonate with you?' I have been told if you wake up tired it can be the spirit world draining you. As what she wrote above this is some of the causes I've also heard for tiredness - entity attachments and spirits latching on draining your energy possibly connected to past lives?? Also astral travel. I've come across all these before. Obviously doctors claim it's just depression, poor sleep patterns, diet, sleep paralysis etc rather than the astral reasons.
