The story will be available from tomorrow - but obviously fans can not wait, and quickly the hashtag was trending with some enthusiastic, and some thirsty, tweets.
A short snippet has gone online, with fans swooning at the simple intro: "Hello". However, most of the clips on the app are from unknown voices.
Check out the snippet below.
"Hi, I'm Harry Styles", our future husband said.
Speaking on SiriusXM, Styles said: "I'm with people who have real jobs, so they're working. which leaves me with not a real job, doing kind of whatever".
"I ALREADY CAN'T HANDLE A 2 SECOND CLIP", one user commented.
Dream With Harry will be available on the Calm app from Wednesday July 8.
"HIS VOICE IS SO SOOTHING I'M CRYING", admitted one. "What do you recommend so that I can be a little bit calmer?". "Yet, instead of making me calm now I'm crying.in a cool way". When trying to refresh the Sleep Stories feature, an error message popped up explaining that the app was "temporarily unavailable".
Even that one sentence - "Hello, I'm Harry Styles" - is enough to make me drop off to the land of nod. A group of emojis-a watermelon, the triple Zs, an open book, the "soon" symbol and a bed-followed by the words "This Wednesday".
Calm, for those of you who haven't tried it, is a meditation and relaxation app with access to recording to help soothe your mind. They also offer a free trial, so what are you waiting for?!
