I have just released my new free online dream journal at
http://www.iAmLucidDreaming.com. There are other dream journals out
there, but I hope what will make this one stand out is that:
1) It is dedicated to capturing information that will be useful to
lucid dreams. For example it allows you to mark potential dream signs
and keep track of how many times they have occurred in your dreams.
2) It is accessed via a gadget on our homepage. We have lots of other
gadgets on our homepage and you can also search the web with Google.
This means you can set us as your own homepage and quickly update your
dream journal as you recall bits through the day.
You can read more about it here:
