Given the premise as I believe that dimension jumping is caused by the shifting of consciousness from one version of oneself and another to better fit with your needs (and to a lesser extent desires) at any given period of time reincarnation seems to me a more logical form of postmortem survival than an after life.
Since in any form of time or dimensional travel a vessel or receptacle ie. a body with a preexisting set of instincts and memory capacity is necessary, the idea of non corporeal existence seems an anathema.
Therefore at the moment of mortal death, the idea of one's consciousness jumping to a dimension where there is a free receptacle, seems far more possible.
This new body if an infant will have course have a more limited brain capacity as the body has not yet achieved optimum potential, therefore a percentage of knowledge is necessarily lost, traumatic events, bad experiences, but conversely skills and passions, important memories carry across and either surface...
Reincarnation is far more likely than an afterlife
