I think that's an excellent idea, pepsibluefan.

You can share dreams with someone without being lucid, of course, but if you want to do it consistently, meeting up while lucid dreaming is the best option. If you feel that your spirit guides will facilitate that connection, it's worth a try. Just try not to think of shared dreaming as something you need another being's help to accomplish. Your spirit guide may make it easier, but that's certainly not the only way.
