This question splits neatly into two very different things — lost objects and missing people — and they deserve very different answers.
Lost objects
Some psychics will offer impressions about a misplaced item: a sense of a location, a colour, a feeling of "look lower" or "it's near water." People do sometimes find these nudges helpful, if only because they prompt you to search somewhere you'd overlooked.
Keep it in perspective, though. As with everything, this is intuitive insight to consider, not a guaranteed GPS, and accuracy varies — the honest framing we hold to in how accurate readings really are. Treat any impression as one more place to look, not a certainty.
Missing people — please read this carefully
This is the part that matters most. If a person is missing, contact the police immediately. A psychic reading is not a substitute for the proper authorities, search teams, or emergency services, and treating it as one can cost precious time. Any psychic impression should only ever sit alongside official help — never in place of it. A caring, ethical psychic will tell you the same and point you straight to the authorities.
Watch for exploitation
Sadly, lost-item and missing-person situations attract scammers who prey on desperation. Be very wary of anyone who guarantees they'll find what's lost, demands large or escalating fees, or claims only they can help. Those are textbook red flags, and the future is never something a reading can guarantee.
In short
For a lost object, a reading might offer a helpful nudge to consider. For a missing person, call the police first, always. A reading is for guidance and reflection — never a guarantee, and never a replacement for the proper authorities. If you'd like reflective insight, you can start a reading here.
