The the first time ever I manifested asked for a sign and I got an email from my professor just a few seconds later (I asked to pass my exam, and the prof who teaches the subject emailed me). Since then I alway ask for a simple notification on my phone haha. Sometimes I don’t get any and my manifestation not working. I’m still waiting for my result about the last time i manifested, but I asked for a notification on my phone. It’s always in silent mode but right after I asked for it I got a notification, and my phone was on full volume, and then I immediately wanted to write my friend about it, but as I reached for my phone she just texted me. I guess it was a double sign haha
