Here is my code.

my $hash1 = $hash0->{unknown}{unknown};
while ( my ( $var, $hash2 ) = each %$hash1 ) {
    ...
}

Am hitting the error "Can't use string ("package") as a HASH ref while "strict refs" in use" when I try to access my $hash1 = $hash0->{unknown}{unknown}from the below hash. 

print Dumper $hash0;

$VAR1 = 
bless( {
    'branch' => bless( {
         'lib/sample/sp.pm' => bless( {
             'branch' => bless( {
                 'lib/sample/sp.pm'=>     bless( {
                     'sample::sp' => '1'
                 }, 'DBM::Deep::Hash' )
             }, 'DBM::Deep::Hash' ),
         'branch' => $VAR1->{'branch'}{'lib/sample/sp.pm'}{'branch'}
         }, 'DBM::Deep::Hash' )
                     }, 'DBM::Deep::Hash' ),
'main' => bless( {}, 'DBM::Deep::Hash' ),
'main' => $VAR1->{'main'}
}, 'DBM::Deep::Hash' );

I went through many forums and my understanding on this error is, will hit this when $hash->{unknown}{unknown} has a string instead of hash (I am dereferencing $hash1 in next step of my code). But I don't see any string values('package' as indicated in error message) in the hash but still it complains. Am getting this error for the statement my $hash1 = $hash0->{unknown}{unknown}; Can some one please help me in understanding the issue.
