It's hard to explain because it isn't like seeing the actual objects I'm about to list - these visuals all morph into each other, and sometimes it feels like I'm seeing an idea rather than an object, if that makes any sense. Using Ganzflicker for about a minute I recall I saw:

- some strange smooth shapes, like two glass hourglasses on either side with oil refracting light, with a blob sliding through the middle of them

- A cat's face

- A forest with non-existent animals running through the tall large-trunked trees

- A palace full of marble columns

- Some sort of grand tower that went out into space, and seemed to branch out like a rope being made

There were all many more abstract things, typically in between (or as a transition between) the more identifiable parts.
