Answer to Monday's Riddle! Real or Unreal?

Fabulous guessing everyone! Excellent job. Yes, all this week we will be slipping into the mysterious realm of dreams. Lizzy's review will send us off into a great story on Wednesday. And, Thursday's Top of the Heap is sure to be out of this world, as we attempt to shed some light on the fascinating landscapes we frequent in our heads. Friday, we will be hosting Grace Lin author of the whimsically, magical middle grade book, Where the Mountain Meets the Moon. So be sure to check back! Catch up with you in a dream, and see you around the book block ; ) ~ F

It's completely dark, and then suddenly it's not. Awareness arises, and thought stirs the lot. Either coming to scare and give you a fright, or sending you sailing into a smooth, lovely night. This place, they say, could never be real. But, when the images shift your mind will reveal; what it is that's inside? or outside? or nowhere? It all depends on the scene that you sew there. For, in your depth is where I dwell, bubbling up fully like the chime of a bell. Your eyes will close, and you will slumber. Forever I'm there to take you asunder. These pieces of you are all that I show- but in the wake of your life, I'm just what you know. 

What am I? Answer: Dreams
