The 4am Mystery: that's an actual thing by the way. Even before a global health crisis took the shape of COVID-19, people around the world were finding themselves sleep deprived, awake in the middle of the night. You might be someone who says, no matter what you do, you just can't sleep. Sometimes you know why: your thoughts are racing, or a nightmare has startled you into consciousness. Other nights, you might toss and turn and, just as you finally doze off, the alarm blares. This book was written for you. It explores why you're awake, how you can manage your mind at night, and what might help if it's your dream content wreaking havoc. Drawing on nearly two decades of therapeutic work, research, and an ancient wisdom proven to helpfully manage the mind, Delphi connects the dots between sleep, dreams and our mental health. She particularly highlights the impact of grief and loss on our well-being, which can ultimately affect the quality of our night-time rest - even if no one has died. Her book guides the reader on a journey to make friends with night-time, learning what the dark might have to offer, to achieve a calmer, healthier, happier life.
