In my initial experiences with the Silent Realm I felt a little spooked, but I was able to easily beat everyone of those missions. Even though I found them easy I still had a blast playing them, and hope they return
I always dreaded doing the Silent Realms, but they got easier to me each time I completed one. I'll never forget the first time I stepped outside that circle in Faron though..and the screen got all weird, and the extremely creepy, adrenaline-inducing music came on!!! Needless to say I ran like a madwoman to get the first tear. Then I relaxed, for a little while anyway haha. I also had several terrifying experiences with waking water and stepping into the light of the floating creatures patrolling the area...
Oh dear. I remember my first Silent Realm all too much. I was terrified. I listened to everything Fi said carefully and was extremely cautious not to get caught in the light, but I kept running out of time and couldn't find the last couple tears. To make things worse, I did not know at first that you could easily get away from the Guardians simply by walking away from them. I thought they were fast enough to catch you, so I held A to sprint the whole time and always ran out of stamina, so then they'd catch me.
I actually failed so many times that Fi said, "Master, the chances of your not being the chosen hero are increasing..."
When I finally found the last tear, it was up on a cliff next to a vine-wall. The guardians were already after me, but I began climbing anyway. I was hyperventilating the whole time, certain that a Guardian was about to come up behind me while I couldn't see them and knock me off the cliff, but none did. I got the final tear and I'd never been more relieved in my life... until I had to go back to the portal.
I just finished the Eldin Silent Realm today and that one was a lot harder. I died the first time quickly, the seconds time was veeerry drawn out. I grabbed a bunch of Tears then realized I didn't have nearly enough time to figure out how to get to the other end. I must have been chased for two solid minutes overall, I kept hitting the air pocket and going up and down the sand slide a bunch of times before I got them all. Then at the last second I wake up a Guardian and thought I would have to start over, I just barely made it.
Compared to Faron and Lanayru, Eldin was way harder and more intense.
