Jolt of consciousness

During the routine in-bed meditation before sleep, I experienced 2 more jolts of consciousness / sensations of space-time warping within. The first one was smaller. The second one, however, was so intense that it startled me a little .. while meditating on the psi pulsing in the central channel, I lost track of space and time for a moment. Came back, verified the surroundings and checked the time. Wouldn't want to end up in a random place at a random time without the ability to find the way back.
