Insomnia is a symptom, rather than a disease, and is characterized by inadequate quantity or quality of sleep. People with insomnia complain of difficulty falling or staying asleep, which results in significant impairment of daytime functioning. Insomnia is categorized as transient (shorter than one week), short-term (one to three weeks) or chronic (longer than three...

You mentioned that your dreams turned into nightmares after you started taking Lexapro...vivid dreams and night terrors are a side effect of some medications, so if your sleep is really suffering because of this you may want to check with your Dr and see if this is a side effect you are experiencing. Perhaps a different med can address your anxiety and depression without the nightmares?
Wishing you the best,

Good feedback from Sonny as usual. Agree that if you are taking meds, your doc may be able to make some adjustments so you're less bothered by the dreams.
And it's worth remembering, as you are, that these are not in fact real. Only dreams, nothing more. You can safely let them go.
More than that, really. Because when you dream, you typically are at the end of one of the 4 to 6 sleep cycles we normally experience each night. That suggests you are getting all the many benefits your mind and body need from good sleep ... even if the content of the dreams are disturbing.
There are people on this board that hardly get any dreams because they can't sleep.
Maybe you can sort of turn this around in your mind as a good thing. That's because maybe through your dreams you are cleansing yourself of the trauma you experienced. You are getting them out of your system through your dreams, so you can heal. In that sense, they are a good thing.
Help me.... (bad joke...hey, it's 3am and I'm tired...)
I'm truly sorry for your nightmares though. I've had them...and they're miserable. Time eventually made mine go away.
I am also prone to various tunes playing over and over in my mind in the middle of the night when I want to sleep. They are quite detailed in mind, I hear them very true to how they are recorded.
These tunes are a form of an occupying thought. Another form of this is listening to sounds, or anticipating noises or sounds of any kind while in bed. Or worrying about your day, past or future. Any occupying thought can fuel insomnia. I've learned over time to try and turn them off ASAP before they really take hold.
There's a number of methods you can use to distract yourself from tunes or occupying thoughts, including the age old method of simply counting sheep. I prefer deep breathing and progressive muscle relaxation.
There's always something new to learn.
