Kundalini Discussion

Has anyone suffered from chronic depersonalisation/derealisation at the time of experiening a spontaneous kundalini awakening ? My son fears if he relaxes/accepts the process he will fall into the "void"/nothingness, as his sense of identity is so fragile anyway (because of the DPD). He has so far not found anyone who has DPD at the time of... (ie rather than "as part of ") the experience of Kundalini and is desperate to find out the best way of working through the process - and any dangers he feels are associated with it. Thanks
