Psi phenomena as tricks

The Ganzfeld experiment seems somewhat similar the NDE OBE, where as the classic NDE OBE is under reduced power with a consequent loss of sensory input, in the Ganzfeld a deliberate attempt is made to still sensory input in a wakeful receiver.  

Some of the RV experiments gave the RV subjects sketches to a judge, who saw both the target, and the unique sketch, and made an association between them. Unique patterns that are shared classically amongst very few people, seem to be able to increase the probability of a non-classical connection between the sharers, as we see in Yoichiro Saka's successful Sony ESP experiments. In my view it's actually exposing things like... how we actually learn.

I'd say OBEs in NDEs are much stronger than Ganzfeld and yeld much more accurate results. The body of veridical evidence for them is really huge.
