Ahlam Al 3asr is feeling like you’re dreaming when you’re not. as a one person who experienced this I can say it is when someone is not used to sleeping in the afternoon which causes them to get sweaty and have weird dreams, happens to the best of us. Now in general, the weird dreams are interesting and unbelievable. So when you see something and can’t believe ur eyes, you can call it Ahlam Al 3aser. 3 stands for ع in 3araby/arabic
Wallahi I can believe my eyes, shinu hatha- shal Ahlam Al 3aser
