I get choked in SP too if I try to WILD. I panick, try to scream for help and when I can't, I realise I'm in SP so I just relax and next thing I know I wake up in a dream

Personally, I prefer this hallucination to the auditory and visual ones. I've learned to identify it as being "one relaxation away from a lucid dream". Problem is, I only sometimes get this one. Usually I get all the other ones and they freak me out more, so I wake up violently shaking. RCs confirm that I'm awake.
