In The Beginning Part 1

After having to clean up all the mess, re-organize all the books in their proper order, pretty much everything that needed to be done that was on the list of things needed to be done. Afterwards, Spike has finally checked off the list of all the chores around the house/library and was ready to take a nap from all his hard work. Twilight was also tired, but she was glad that everything was neat, tidy and organized and for that, she decides to get to her studies on the spell books so that she can improve on her magic. So she goes through the shelf to look for a spell book to look at so she can learn the spells on there, while she was looking through the shelves, she stumbles on a black spell book that she had for a while now and has never bothered to look into it.

This book contains some of the old spells that she has never learned, spells that have never been used in a long while and of course, certain spells that are considered forbidden for reasons unknown. Ever since Twilight had moved into Ponyville, she placed this book somewhere in the shelves, away from plain sight and has never even bothered to read it and pretty soon had forgotten all about it until now, only because she was busy learning spells from other books, studying for her exams and solving friendship problems. Anyhow, she's now about to take a gander into the book so that she can see what amazing spells lie inside the book.

She was looking through the pages, so far she was rather impressed at what this book had to offer, especially this one particular spell which was known as the "dream-scape spell." As always of being a unicorn of curiosity, Twilight uses this spell to try to enter into her own dreams so she can see what she dreams about when she's sleeping. Then there's Spike, whose not so sure about Twilight performing this spell, he feels that there might be something wrong with somepony trying to sneak into other pony's dreams and thoughts. But then, Twilight tells Spike that she's only going to perform the spell to get into her dreams and thoughts and no pony else. And even though Spike still wasn't sure about Twilight going through with it, he lets her do it because she's only going to use it to go into her mind.

So now that she's got this spell in the back of her head, she's ready to perform it, however she's a little nervous about having to use it considering... that this is her first time having to use this spell. Anyhow, now that she's stopped being nervous, she clears her mind and focuses on the spell. Her horn started to glow, she was in deep concentration and then... she pulls out a blank expression. Spike was a little worried about Twilight and the spell that she performed, he notices that her eyes are glowing white, she wasn't moving even moving an inch, she was just standing there. She wasn't saying a word or doing anything else, even Spike tried to shake her so that she can snap out of it. But nothing happened, she was still the same, no expression, nothing.

Now as we go through Twilight's eyes, notice how her glowing white eyes turned back to her normal purple eyes, pupils included of course, and then she was looking around and she notices that she's still back in her own home/library. However, the only thing that was missing in the room, was Spike. She was calling out to Spike about 4 times and he hasn't shown at all, she looked around the whole library and still wasn't there. Then, she went outside to see if he was out there, but still he was nowhere to be found. Twilight wasn't sure that if the spell even worked, but then she also noticed that it's day time and last time she checked, it was night time when she was cleaning the library and re-organizing books. And so she finally came to the conclusion that the dreamscape spell actually worked, and of course she was happy to see that she managed to perfect the spell.
