This happens somewhat often to me under fairly specific circumstances. If I wake up after I've been asleep for a few hours and then fall back asleep I occasionally have very vivid and sometimes lucid dreams. They're very realistic but something will clue me into the fact I'm dreaming

I've learned to recognize things that alert me to the fact I'm dreaming. Usually it's when I try to write anything on my phone like entering a phone number or texting. It just doesn't work; it's just gibberish. But when things are too strange and I realize I'm dreaming I "wake myself up" while I'm in reality still fast asleep
