They are probably about to . It is available in Chrome Canary but it ' s experimental with lots of bugs <| sep |> Happens to me too from time to time . It ' s usually around dreams that have recurring themes somewhere inside of them , and that theme will link memories of past dreams together . For example I sometimes dream about elevators that go sideways and diagonal . Thinking about one dream fragment like this brings up other dream memories . These others sometimes have other themes . I can sometimes then follow these other themes to even more dream memories . Most likely to happen when I ' m very sleepy , either waking up or falling asleep . It ' s really freaking cool , like a whole dream recall network of thematic associations . That said , it ' s also possible that , in a sleepy state , my brain can ' t really distinguish between remembering a dream and kind of having one , me that what strike me as memories maybe aren ' t .
