Here's my idea of the picking for one of my fave songs of all time ;)

C (x32010@1)              E (022100@1)              Am (x02210@1)             FE|--------------------------------------------------------------------| (133211@1)B|--------------------------------------------------------------------|
G|---0---0---0---0----1---1---1---1----2---2---2---2----2---2---2---2-|
D|---2---2---2---2----2---2---2---2----2---2---2---2----3---3---3---3-|
A|-3---3---3---3----2---2---2---2----0---0---0---0----0---0---0---0---|
E|--------------------------------------------------------------------|

C (x32010@1)              E (022100@1)              Am (x02210@1)             FE|--------------------------------------------------------------------| (133211@1)B|--------------------------------------------------------------------|
G|---0---0---0---0----1---1---1---1----2---2---2---2----2---2---2---2-|
D|---2---2---2---2----2---2---2---2----2---2---2---2----3---3---3---3-|
A|-3---3---3---3----2---2---2---2----0---0---0---0----0---0---0---0---|
E|--------------------------------------------------------------------|

Just play this throughout the song and when you get to the "There are no legible signs" 
and "you're not in the room" parts, play this;

C (x32010@1)     E (022100@1)     F (133211@1)             C (x32010@1)     E (022100@1)     FE|-----------------------------------------------------------| (133211@1)B|-----------------------------------------------------------|
G|---0---0---1---1---2---2---2---2---0---0---1---1---2---2---|
D|---2---2---2---2---3---3---3---3---2---2---2---2---3---3---|
A|-3---3---2---2---0---0---0---0---3---3---2---2---0---0---0-|
E|-----------------------------------------------------------|

Have fun!!! :)
