Dreams

i think someone told me once to drink tea before bed...

but, i don't know. if they get really bad and you can't sleep, maybe you should see your doctor about sleeping pills...

 

I recommend seeing the movie waking life for information about dreams.
Clearly your body is trying to tell you something...but if you don't want to do anything about it try to think of positive imaging before you sleep.

 

I find warm milk is good for helping you sleep. Not too much though, just a small glass.

Tea isn't so good because it contains caffeine which is a stimulant. Though if it works for you then that's fine.

A bath is good, or just sitting around relaxing, reading, watching TV or whatever. It helps to unwind and relax a bit before going to sleep. I find reading in bed is a good way to help me doze off.

 

Also listen to soft music that help relaxing yoru mind, especially instrumental music, which help develope your thoughts, peaceful music help you falling to sleep in a relax way

Or I have read soemwhere just do excersise,it'll help your blood flow equally in every part of your body, one of the reason that we dream is because we didnt spend all the energy for that day, so exercise also help you to spend all of that energy, after that you'll feel like you wanna sleep, but dont do too much, also take a bath.

Nightmares/dreams are also caused by your posion while sleeping, when you sleep in a position that block your blood flow at any part of your body, like put u head on your hand or in a curve position

And nightmares also caused by your thoughts, but if you dont think liek tat, and it just continues to happen to you everynight, need to see the doctor or pshychologist
