Particular & Form won’t work together like that as you probably have discovered. While they both can use and interact in AE’s 3d space, they are both 2d effects and they don’t have the ability to measure the distance a flowing form shape is from the camera, or what direction it is flowing. All Particular will see is a white alpha channel that indicates it should put particles at that location, it can not discern which way the particles should be moving based on the movements of another layer.
This is something you might be able to accomplish in a 3D modelling application like C4D, but not truly in AE.
Perhaps you could fake it with multiple form layers, using the same fractal patterns. The top layer would have a lot less particles and the fractal could displace them quite far in distance.
