T'was all D. SWIM smoked the D with MDMA and K still washing around in his system, although he wasn't 'on' them if you see what I mean.

I've never had anything approaching that intensity or being that all encompassing on acid. When I say meta-hallucination I mean that I was 'there' as it were, but also witnessing it from a distance. Hence it was a hallucination inside a hallucination. At the time I didn't really feel that what I was 'watching' was a 'hallucination', more a glimpse of the future.

It's not something I would necessarily suggest people do but for the record SWIM has had some excellent experiences after a night on above drugs. Probably because serotonin levels are still high etc. 

I would also say though, that, depending on how heavy your night before was, you may be quite mentally tired, which is not really a good time to approach D.
