I have the same problem occasionally, one way I found how to get out of it is to like rip my eye lids off, that actually did work for me once, another is try to see through your eye lids, just close your eyes completely (sometimes I have like a part of one open and thats all I can do) and really just try and let everything come back to you, or you can lay down and start the dream over again, or you can try to visualise the scene yourself, you have good skills of visualisation in dreams if you do it right.
