The Hallu rays are godrays that have a color to make the effect punchy. In Motion FX you have the steps to drive the number of frames that will be used to expand the effect and smooth it with the 1st pass and 2nd pass of vector generated motion blur. The blend is here to make sure that you can tweak the transition between hallucination and original image.
