This article talks about "sleep hygiene." https://sleepfoundation.org/ask-the-expert/sleep-hygiene This stuff is easier to say than to do! Some things that are helpful: a) Establish a fixed habit pattern or ritual and stick to it. b) Make the bedroom really dark. Get new shades if you need to. c) Get exercise every day. d) The effects of coffee last longer than people thin, really cut down on coffee in the morning and don't drink any in the afternoon. e) Avoid looking at TV or computer screens late in the evening; if you know how to set the color temperature, set it to as warm a color temperature as possible to reduce blue light; consider using one of the no-cost anti-blue-light software programs like f.lux. If it seems like a serious problem to you, considering getting a doctor to refer you to a sleep lab and get a "polysomnography" test to make sure you don't have a medical problem that could be treated.

Try to relax (by listening to the music, reading, etc) and drink a glass of milk. Also, pray your God to give you sweet dreams. I think it can help.
