Listening to your example, compare the Deftones' "Knife Party."

From the description - hypnogogic pop? Tame Impala, especially anything off Currents. An album that begins with "Let It Happen" and ends with "New Person, Same Old Mistakes."

Kinda progressive rock, especially post-70s. Kingston Wall - "Could It Be So?"

Songs that make you lose yourself before the voice of the artist jolts you awake.

Oh, so more My Morning Jacket. "Touch Me I'm Going To Scream, Pt.1." "Dondante." Or arguably Mew's "Comforting Sounds."

Big shoegaze fan here. Give decayfm.com a listen. I didn’t see Slowdive mentioned but you should give them a listen.

Not sure if this will be what you're after, but the first thing that reminded me of is Goodbye by Apparat (although that's a bit slower than the tune you linked).

Ten Thousand Years Won't Save Your Life by the band Hammock is like this, I wouldn't call it alternative, but wow, it opens up, takes you on a trip, gently sets you down.
