Unusual or experimental prose

If you like surreal humor, INCIDENCES by Daniil Kharms is a bit insane. (Or pretty much anything he writes.)
Just slightly in the same vein as John Lennon's books--and probably an influence.

It's easy to see he also influenced some modern bizarro writers like John Skipp and D. Harlan Wilson.

This is what he looks like:

 

I'd go with House of Leaves. Other Danielewski's novels , I think, also are written in an experimental style.

 

Geek Love by Katherine Dunn has a prose style that is a little off-centre.

 

Additionally, Ada or Ardor: A Family Chronicle by Nabokov fits the bill.

 

is isk a experiment... ?
