I think I've developed insomnia. 🦉💤 Does anyone know how to fix it?

I've been experiencing déjà vu for about 10 years. I remember seeing a whole exam question paper, mostly in dreams or while thinking. The last thing I recall is being sentenced to death, and my friend was sentenced too. I'm scared; is this my future? Can anyone here tell me about this?

I know that m1u1 + m2u2 = m1v1 + m2v2 Can any one prove that to me.

It is the 20th ramadan and i didn t complete a single chapter. Please help me with this. I have work from 8 am to 11:30 am
