There are ways to enhance and remember your dreams some are easy some are just fucking confusing.When i want to remember my dreams i meditate before i go to sleep and when i'm meditating i'm just clear my mind and relaxing myself  then i put my amethyst underneath my pillow and the reason why i do this is because the amethyst clears your mind so you can focus more in your dreams and remember some of it or all of it.

My amethyst looks similar to the upper rights side of it

My other one looks like the inside of this and is smoothed on the outside as well but not  circler 

I wish i had one one that looked like this 

I will be getting more into the many uses of crystals and there meaning
