What does it mean if you keep yawning over and over aain?

Should I go to bed if I keep yawing over and over again. I never have yawned this much . - yawn. Idk if it's because I am bored or if I am tired. Should I go to bed just in case now?

Boredom, tiredness, not getting enough oxygen to your brain (mostly happens to singers) or even low body temperature.

Any of these things could be a contributing factor to your continous yawning. Try doing something to keep your mind occupied in case you are bored, try deep breathing and if you are still yawning then cuddle up in your bed and get some sleep.

You are most likely going through heroin withdrawal, as excessive yawning is the primary symptom to first present itself in patients.
