This is known as Deja Vu occurrences, the feeling that you are experiencing a situation that you’ve been through before at other levels of reality. These usually happen when we experience a shift in consciousness. As the Veil is merging within our multidimensional self we have these occurrences because past-present-future is unifying together so our memories are merging together. I also see these experiences as a symbol of change. Watch your thoughts and actions during these times, it’s usually a sign of a shift in conscious understanding. For instance we were out shopping and i was trying to park but every row i turned down a car kept stealing our spot, this happened three times in a row it was really trippy. I saw this as an experience of acceptance and slowing down. We have these deja vu moments because they are like glitches in reality, it means change, a change in awareness, a change in circumstance a change in inner knowing. the more you see, the more you question the more you know 😉
As for your brain never fully shutting off, this is also just part of shifting energy, it sounds like your consciousness is going through deep changes within yourself and your dreams are telling you so. As the veil is thinning and merging, our dream world is changing because our consciousness is changing. everything interconnects because the dream world is our inner subconscious, and waking reality is outward projection of experience consciousness. So symbols and memories in our dreams can be carried out into waking reality and vice versa as they interconnect. As we become more consciously aware our dreams can change shape because our consciousness is changing in the understanding of itself and it’s memories. It’s kinda hard to explain i hope this makes sense lol.
much love <3
