Reality check, then shaking?

When I do WBTB I get in a vivid dream and if i do a reality check in the dream i wake up in a SP and start shaking. This one time my room turned purple with a circle in the middle where the colors were the normal colors, while i was shaking. I don't seem to get any further than this, help? It feels like some guard is protecting the dream world and won't let me lucid dream. Once it actually felt like reality got really pissed off at me for playing with it......

Well, SP normally comes with halucinations, I doubt there's a guard to the dream world too lol :) Also you might have been in a FA, but if it was SP, you should be able to go straight into a dream from there.
