Srimad Bhagavatam 6.17.30

6.17.30

अविवेककृत: पुंसो ह्यर्थभेद इवात्मनि । गुणदोषविकल्पश्च भिदेव स्रजिवत्कृत: ॥ ३० ॥

aviveka-krtah pumso hy artha-bheda ivatmani guna-dosa-vikalpas ca bhid eva srajivat krtah

aviveka-krtah
done in ignorance, without mature consideration
pumsah
of the living entity
hi
indeed
artha-bhedah
differentiation of value
iva
like
atmani
in himself
guna-dosa
of quality and fault
vikalpah
imagination
ca
and
bhit
difference
eva
certainly
sraji
in a garland
vat
like
krtah
male.

As one mistakenly considers a flower garland to be a snake or experiences happiness and distress in a dream, so, in the material world, by a lack of careful consideration, we differentiate between happiness and distress, considering one good and the other bad.
