Since this is a ghost costume?

The target was definitely on the other side of the wall, and with the whole situation already lasting a long time, Lauren was about ready to try anything.

By anything, she, of course, meant walking through the wall. She was wearing a ghost costume after all. Right?

She slowly touched the wall trying to be as immaterial as possible ... and to her shock and surprise ... it went through!

Step by step she inched towards the wall, she could not see what was on the other side, but the feeling was like she was pushing her hand through the water. Practically no resistance.

Her face was getting close to the wall. Scarred what getting through the wall might feel like, she decided to jump over. She crouched. Jumped.

Shliematakadamauratamikagha spoken by a deep, old, manly voice, was the last thing she heard before fading into black.
