[Vocabulary] to be spaced out - to be zoned out

[dilodi83]

Dear teachers and native English speakers,
can you explain through some easy examples the differences between these two phrasal verbs...? I cannot understand how you use them.
Thanks so much.

They seem to mean much the same, though I don't use 'zoned out'.

Spaced out

Zoned out
