the lack of trousers/coat is placing you in
a more natural state;
you've got no [less] barriers placed between you and 'the world'.
you have a "top" which you'd wanted to pull down, covering your
lower portions... this might be an effort to extend your intellectual
understandings into protecting your 'baser' instincts [ineffectually].
the dog here seems to be representing your 'spiritual guides'
(loyal companion), who are unable to communicate [directly]
with you due to an 'injury' of some kind.
the roller coaster idea is speaking of profound 'movements' due for
you on the horizon (in the near term i figure). Will is always in
motion, and never static -- it's quite good to have it unencumbered
by judgmental thoughts (naked and unafraid).
My dog was jumping around pawing at one side of his mouth as though he'd hurt himself and while I was trying to look he was dancing around. When I finally got hold of him he wouldn't let me look in his mouth. He jumped up on a bench and sat down but a lady came with her dog and it also climbed on the bench at which point my dog went to bite it. I was apologising to her when the next thing, I was sat on the bench with my dog and another person on their own (not the woman with the dog) was sat right at the other end and we were moving, getting faster like it was a rollercoaster. I was trying to lift my feet up so they wouldn't scuff the floor and I was holding on to my dog scared he'd fall off.
