If you want to type up the dream journal and have it private you could also save word docs of them, and then to store them online you could use a site like dropbox. Or you could just type them up here on the site.

I'm currently taking taking college classes and I don't find it hard to balance it with LDing. It's not really that time consuming, I can work reality checks into my normal schedule, and if I was keeping a dream journal it'd probably take me about 10 minutes to do in the morning.
