'dreamland' originates from the combination of 'dream' and 'land', where 'dream' meant 'a series of thoughts, images, or emotions occurring during sleep' and 'land' referred to 'a realm or domain'.

'dreamland' evolved from the Old English word 'drēam' meaning 'joy, mirth, or music' and 'land' from Old English 'land', eventually forming the modern English word 'dreamland'.

Initially, it meant 'a joyful or musical place', but over time it evolved into its current meaning of 'an idealized or perfect place'.
