Drink it! or else!

I'm about going out from one club, and i found my Sensei at the university with his friend got drunk and lean to my sensei. I came over him and say
Me: "Sensei, is it everything alright? Your friend seems not so well"
Sensei: " Syameel, have you meet (I forgot his name was) ? He is one of my friend (i forgot the details, but let say that he is a friend from my sensei' past workplace.....) bla... blaa...."
Me: " Nice to meet you. Are you alright sir? do you need something? should i call you a cab?"
That friend of my sensei: " Its alright, come join us, what about you.. take me more shochu!(japanese sake)"
Me: " I'm concern about you sir, are you sure you wanna..."
Sensei cut the conversation.
Sensei: " Syameel, can you just take the shochu for him!"
then i took the shochuu, 2 cups of sake, for him and for my sensei.
That friend of my sensei: "Hey, why don't you get some too?"
Sensei: "Yes Shameel, you HAVE TO get some japanese sake. in Japan, it is rude if you refuse other person favor, isn't it?"
Yea.. yea.. yea... in japan... blablabla....
I just nod.
Me: " OK ill order the shochu."
Sensei: "Wait, why dont you accompany him while i get it for you."
Me: " Really sensei? you dont have to do that.."
Sensei: " I insist!"
sensei came back, brings one more cup of shochu. I took it awkwardly. We all cheers
All: "KANPAAI~"
Turns out that sensei gave me a cup of plain water, a water... ooh thank God. Sensei knows that i feel uncomfortable with the situation. but he gave me a water instead of shochu. I drink the shochu really fast and uncomfortably.
That friend of my sensei: " Hey, how come you drink that fast, its a really high alcohol one! Unless...., its NOT SHOCHU that you drink!"
Me: " silence"
That friend of my sensei : "Give me that drink!" and took the glass and drink it.
Still him : " This is not shochu, are you trying to fool me or something?"
oh my God... of my God.... he realize it!!! oh my God.....

Then i wake up from my sleep, OMG its a dream!!!!??? for real????? what a really weird one! then i rush myself into bathroom, preparing myself to go to morning part time......
