Abruptly, Jenna can't feel her body. She can still see somehow. There's some sort of semitransparent cerulean passage tube which twists and turns as her disembodied self races along it. She can also hear, there's a sort of whistling sound as if things are whizzing past her at extreme velocity. She can see what might be stars through the edges of the passage but stars definitely aren't supposed to move that fast. If she's ever been on a rollercoaster the experience probably reminds her of that.
And then just as suddenly she can feel her body again. She feels a bit of a chill and is forced to take a few steps from sudden unexpected momentum. Around her is a grassy clearing. The chill quickly abates with the feeling of a sunny summer day blooming across her skin. There's forest not too far away in all directions. Closer at hand there's a pedestal about waist high and a meter across. There's a few glowing lights on it she can make out. Behind her, there is a metallic ring of some kind. There's seven large glowing triangles around the rim and in front of each of them is set further inwards is a collection of dots. The interior of the ring is likely much more eye catching though. It looks almost like a pool of water except it's vertical and it's glowing.
