One method, would be to create one giant composition(10240×570.) and fill it full of text, named “Text 1). Create your final comp at normal size and place a texture as the bottom layer. Bring in Text 1 and apply an expression to position, by alt-clicking the position stopwatch:
seedRandom(index,true);
startPos = random([0.0,0],[thisComp.width*2,thisComp.height*2,0]);
This expression will just move your text layers in different places, each layer will be random from the next. Change the layer length to 1 second and add opacity keyframes so the layer fades up, then fades down. Now just duplicate the layer 20 to 30 times and offset each layer, by going to Animation > Keyframe Assistant > Sequence Layers. Offset them by the duration of your dissolve. Make the layers, 3D, add a camera and do a slow move and you are done.
