This happened at the training camp you were fighting to get Bakugo back from the LOV...you used too much of your muna to over-used your quirk power......till then you got Bakugo back from being taken from the LOV as they try taking him through a weird dark purple warp portal but you felt tired till then you fell on the ground unconscious into a coma but you try keeping your eyes open as Bakugo comes over to see if your okay...

Bakugo: {{user}}! Stay awake for me!

{{user}}:......H Hushabye Mountain...........

as then you said those words you have gone unconscious into a coma for bakugo was confused of why you said those words as then class1-A and 1-B were safe from the LOV attack at the Training ark camp till then you were sent to the hospital to be check on and safe as your in a coma your classmates from Class1-A always come to see if you wake up soon and for Bakugo . . . he was thinking into his mind of why you said those words Hushabye Mountain he told aizawa about what is Hushabye Mountain and why i said those words for, Aizawa looked it up in his computer as it show what it is and this what it says ( Hushabye Mountain is a dreamland for all people who go into comas, as it’s a lullaby from a movie called Chitty Chitty Bang Bang, a 1968 film that could soothe worries and anxieties away. As the people go into a coma, they’ll appear in a boat as they sail to the mountain called Hushabye Mountain. ) as they see what it says they became shocked of why I said Hushabye Mountain they thought and thought till getting an idea what if they try to go into the place called Hushabye Mountain so then Bakugo and Aizawa told the others meaning rest of class1-A and even Present mic to show what the plan is as they agreed they gone to the hospital to tell the doctors and nurses to see if they could make them gone into a coma till find me in the Hushabye Mountain, the Doctors and Nurse were scared to do this, but agreed to them about this plan as then they took them into the room where I am in they waited for the Doctors to bring the injections to make them go into a coma, till then the Doctors and Nurses came in the room with the injections as they started putting into their skin to inject the fluid inside them till then they gone unconscious going into a coma as they Bakugo wakes up somewhere misty he sat up till looking around to see he's in the Hushabye Mountain as then he notice he was in a boat just as it said in google he looked around to see the others here in the boats their in as then they came upon the land of the entrence of the Hushabye Mountain they were shocked to see as then it was really real till then they have to try to find you on the mountain of Hushabye Mountain........
