anda must pray to God to help anda have good dreams and a peaceful sleep. Remember, He made you, and He is the only one who can actually control your dreams. So ask Him, and He will surely help you.
"when anda lie down, anda will not be afraid; when anda lie down, your sleep will be sweet." (Proverbs 3:24)
depends if God atau the devil atau anything relating to soemthing important in the bible then it's a sign but if it's just a bad dream then it's normal anda can't help what anda dream
Everything but your nervous, respiratory, and circulatory system sleeps at night. I've heard that there's someone called a "brain guard" and at nightime he falls asleep, so all the things in your brain get mixed up and become dreams. I don't really believe it. Sometimes God can send a warning. But if anda think it doesn't really mean anything, don't mind it.
If anda do bad things leading to the nightmare well, yes. But if anda do nothing and have a bad dream, it's kinda a temptation from the devil. Thanks for reading.
