Meditation before bedtime. Are you totally alone at bedtime? If not, make sure you are. This would include any animals! You know that state you go into when you day dream? Get to that for 5-10 minutes. The way I do it is sit in the bed and focus on something across from me. I close my eyes to the point of blurring everything up and just relax. Try to clear your mind of anything and everything. It's going to be hard at first. But put an image in your mind to concentrate on. It can be an image of a leaf or a bird or whatever you want and like. When you find yourself veering off into thoughts or picturing other things, go back to your chosen image. As I said above, try to do this for 5-10 minutes, longer if it you need it. All this is doing is helping to relax your mind.
To help get rid of negativity while you are sleeping...this is something I do and it does help. Get a glass...make sure it's one you won't use anymore in daily life. Before going to bed at night, fill it with water and put it somewhere near your head. The water will absorb any negativity while you sleep. (You can do the same thing with the egg. I'll explain that one later) When you wake up in the morning, take the glass in your less dominant hand (left if you are right handed, etc) and pour the water in the toilet. Wash the glass 3 times with water and pour it each time in the toilet. All you have to do is swirl the water around in the glass. Once you've done this, flush the toilet. This will flush the negativity away! Repeat this every night and morning for as long as you need to. For me, it took about 2 weeks and I realized I was sleeping much better!
As far as the egg goes...get an egg and place it near your head (if you do the glass of water, you can place it next to it) Leave the egg there for 7 days. If it breaks before that 7 days, it is said that the egg as absorbed a LOT of negativity! Just toss it (described below) and get another one. If it lasts the full 7 days, on the 7th day, take the egg to the bathroom. Toss is hard enough into the toilet so that it breaks and flush it!! If it doesn't break the first time, try it again until it does break! You might notice that the egg is larger than it was when you first got it out. This is a sign of the negativity it's absorbed.
