Congrats on one week! It's eerie how much I can relate to your post. When I'm detoxing I hear stuff that isn't there as soon as I lay down. I think I hear someone knocking on the door or a TV playing from the living room. I also have really lucid dreams once I do fall asleep. I tend to literally jolt out of sleep once I'm relaxed. Hang in there, this will be over soon. Try listening to sleep talkdowns or meditation on YouTube before bed (through earbuds) and practice deep breathing. Wearing a sleep mask and laying on a heating pad works well too.
