As vagrant dreamer described we all share a collective consciousness. What we do not share is a single way we percieve things. Everybody takes in and interprets information differently. So while I'd suspect you might have some success attempting to share dreams the more specific the information is you're attempting to convey to one and other the less likely you are to get it to work because niether of you will interpret the information the same way. What might work better is a picture or something visual. The information of the scenery in a picture is far more subjective than the matterial written in a book and I think it'd be much easier to find similar interpretations of the same information.
I'd also suggest that you both create a key word or mantra designed to put you both on a similar state of mind. Then fall asleep at the same time as well.
If somebody is interested, sometimes while lucid dreaming I meditate on top of Everest at about 3 in the morning or so. The place can be reached at any time. You know you've reached my spot if you find two oblisks at the sides of an arcane circle burnt into the ground. I don't want to share colors or scripts because that gives the game away. Your "key", or pass for access is Mt. Everest, 3AM by two oblisks and an arcane circle burnt into the ground. Anybody who is interested should try to visit this spot then pm me what you see. Its important that you send me your report via a pm so that you do not taint the minds of others. I will then say who was the most accurate.
