it is a book with your dreams both wrote out and drawn out. they can be anything from paper glued together to a hardback blank book. they can have fancy ink to just a pencil. the only thing stoping it from being itself is you. you are the creator of this book, and may decorate, write, and draw in it as much as needed..
using a dream journal
when you write in it, you want to be as detailed as possible. the best time to write in it is withen 30 minutes from when you woke up. and if your drawing, add as much detail as possible. make it seem like you had just dreamed it.
you then can take your journal and get the dream interperted or interpert it yourself, using every detail. remember an interpertation is an opinion on what it means, for to one person it can be good, but to another it could be bad. also be careful who you share a dream with.
