So last night I somehow managed to consciously switch back and forth between a waking and a dream state; perceiving my actual bedroom one moment, and a different bedroom in a dream the other moment, and back and forth like that at will.

This involved deliberately inducing/ending sleep paralysis as well.

I have previous experiences with lucid dreaming, but this is definitely a new level of control over the process - it was like I had a KVM switch that could arbitrarily switch out what my senses were connected to, my actual senses or 'simulated' senses in a dream.
