Connected to an idle instance after computer crash

Question

I was inserting rows as following
begin
for i in 1..10000000
loop
insert into test values(i, dbms_random.string('U',50), dbms_random.string('U',50), dbms_random.string('U',50), dbms_random.string('U',50), dbms_random.string('U',50));
end loop;
end;
/All of a sudden my computer crashed after an hour.
I did a reboot and I am not able to use my database anymore. What did happen and how to repair it?
I started database instance ORCL and it's listener and all I can see is:
