What is 'REAL' ?

Is something 'REAL' which you can;
SEE through your EYES?
HEAR with your EARS?
SMELL with your NOSE?
TASTE with your TOUNGE?
TOUCH with your SKIN?

Or is it enough if you just can only FEEL it is 'REAL', in case;
other people can't SEE it?
other people can't HEAR it?
other people can't SMELL it?
other people can't TASTE it?
other people can't TOUCH it?
other people can't SEE it?

It is all in your MIND
Which one is REAL or UNREAL
