Why Is My Snake Plant Curling?
Curling leaves are a stress response. The cause is almost always one of three things: light, water, or pests.
Curling inward = thirst or heat stress. Curling downward at the tips = overwatering. Spotty curling with stippling = spider mites.

Three things to check, in order
Underwatering or heat stress
Plants curl leaves to reduce surface area when stressed by heat or drought. Common near sunny windows in summer or hot AC zones in winter.
Fix: Move away from direct heat source. Water thoroughly, let drain, resume normal schedule.
Spider mites
UC IPM data: spider mite damage causes stippled, dusty appearance and curling. Look for fine webbing on leaf undersides.
Fix: Rinse plant in shower with room-temp water. Follow with insecticidal soap spray every 3–4 days for 2 weeks.

Low humidity
Tropical species (calathea, prayer plant, anthurium) curl when relative humidity drops below 40%. Common in heated winter rooms.
Fix: Run a cool-mist humidifier near the plant. Pebble trays help marginally; humidifiers help a lot.
