Squirrel gains access to a psychedelic oak tree in the sky. By Jason P. Ryan. Jason also did the effects for this pretty cool acid trip sequence for a comedy series:
Benjamin did some 3D animations, printed them out and messed around with the prints with watercolours and stuff. Sure makes that CGI look lots more organic.

Bimbo gets sucked into an Inception-like initiatic journey where nothing is what it seems.
Cool abstract hand-drawn (and some stop-motion) effects animation piece by Chris Casady. Composited effects by Chris can be seen in Tron (1982) and The Adventures of Buckaroo Banzai Across the 8th Dimension (1984). Check out his Youtube channel for fascinating effects sequence breakdowns.
The fluidity of the work brings to mind a possibility of visionary inspiration.
