The dude your supposed to talk to should not patrol, the first time I went under there everyone turned hostile because I just walked in and the patrolling dude wasn't nearby
Oh and at the moment there is no reason to use Synesthetic Refocus over a normal headband besides looking for secrets, I would suggest increasing the psychokinesis boost to 50 (this isn't too much since a headband has lots of other strong boosts) and making it increase force field health or something like that, since they use force field to attempt climbing the Oculus
