I recently started meditating about 20 minutes in the morning and 20 minutes in the evening. I've been sleeping much better and I can remember my dreams more easily. I also notice that I generally feel much more relaxed. It's not a cure all but it really does help.

I do not prescribe to any of the spiritual/pseudo-religion around it though. In fact, if it weren't for the noticeable benefits the 'religion' would have scared me off. There are different types but I'm more into the vedic/mantra and breathing exercises.
