A premonition refers to a situation when future events are foreknown or forecast. However, the distinction between precognition and ordinary evidence-based predictions is sometimes not made sharply. "Premonition" may be defined to include or exclude ordinary predictions, and this means a fallacy of linguistic ambiguity can lead to an overly supernatural explanation for predictions' accuracy. The following are instances on LOST in which a character has predicted or referred to an incident before it occurred.
Prior to Flight 815 Edit
| Malkin's Knowledge of Aaron
At the advise of a friend, Claire visited a psychic named Richard Malkin, who informed her that great danger surrounded her child, and that her child must be raised by no one other than herself. After months of harassment by Malkin, Claire finally agreed to meet with him to here his plan, which was her letting a couple of "good people" in Los Angeles raise her child. However, Claire later discovered that Malkin knew the plane would crash with her on it, thus ensuring that her child would be raised by her.
| Desmond's Past
After turning the fail-safe key inside the Swan, Desmond appears to relive certain events from his past, and is able to make certain alterations. Desmond attempts to purchase an engagement ring from Ms. Hawking, however, she contradicts him and tells him that it was not how things were supposed to play out. She informs him of how he leaves Penny and flees to the island to push the button, and then turn the key, and that if he doesn't every single person would die.
On the IslandEdit
| Bernard Being Alive
After the crash, Rose became distant from the rest of her survivors. When Jack reached out to her, Rose spoke about her husband, Bernard, to which Jack asked if she wanted to say anything about him at the memorial taking place that night. Rose stated that her husband was not dead, and that the Tail Section survivors were probably thinking they were dead as well. Rose turned out to be correct, and she and her husband were reunited.
| Claire Being Attacked
Claire has a premonition about her child being kidnapped from her, as well as wandering through the jungle and seeing a crib with an Oceanic Airlines mobile hanging above it. Claire and Charlie would later be kidnapped by Ethan in All the Best Cowboys Have Daddy Issues. Claire also saw the plane mobile inside the Staff Station in Maternity Leave.
| Shannon's Death
After Boone told Locke that he was going to tell Shannon about the hatch, Locke knocked Boone out and applied a substance to the back of his head. This induced a vision which depicted Shannon being chased down and mangled by "The Monster". Shannon would later be killed by Ana-Lucia in Abandoned.
| The Beechcraft and Boone's Death
Locke had a dream about a Beechcraft crashing in the jungle, as well as Boone, covered in blood, repeating the phrase "Theresa falls up the stairs; Theresa falls down the stairs." Locke, later asks Boone who Theresa was, and he explains that it was his childhood nanny, whose death he feels responsible for. Boone and Locke finally arrive at the plane which is perched in the canopy. Boone climbs the cliff, and inside the plane he finds a radio, which he uses to contact Bernard for a few seconds, before the plane falls to the earth, with Boone inside. The fall sustains great injury to Boone, so great that he dies as a result.
| Walt's Concern About Sharks
While building the raft together, Walt makes a comment about whether or not the raft would be attacked by sharks, to which Michael replies "shark's not getting anywhere near us". However, the raft was later witness to a shark attack in Adrift.
| Walt's Knowledge of the Hatch
After Michael was accidentally poisoned by Sun, Walt confided to Locke that he was not responsible, feeling that Locke might have though he did, since he burnt the first raft. Locke states that he didn't tell on him before and that he wasn't going to tell on him now, and that he would never do anything to hurt his dad, and placed him hand on Walt's wrist, at which point Walt pulls away. When Locke inquires as to what was wrong, Walt replies "Don't open it." and "Don't open it, Mr. Locke. Don't open that thing.", when Locke inquires as to what he was talking about, Walt replies "Just don't open it.". Walt was referring to the Hatch which would be opened by Locke in Exodus - Part 2.
| Visions of Walt
Shannon saw Walt on three seperate occasions. The first occurred while she was searching for Vincent in the jungle, and came across Walt, soaking wet, who said "Don't push the button. The button's bad." backwards. Walt was referencing the button inside the Hatch which the survivors would soon discover.
A second occurrence was when she was post-coital with Sayid, and found Walt standing in her tent, and then said "They're coming and they're close" backwards, referring to the Tail Section survivors.
The final occurrence was in the jungle with Sayid, who also saw Walt, and the two watched as Walt made a "shhh" noise and motioned with his finger. Shannon would be killed seconds later by Ana-Lucia.
| The Baptism of Aaron
Charlie began to have dreams about Aaron in danger, and sought out Eko's assistance. Charlie then decided that the baby needed to be baptized, and one night, set fire to the camp to distract them from the kidnapping of Aaron.

| Ana-Lucia's Death
While having a dream about building his church, Eko sees a vision of Ana-Lucia inquiring about why he was building a church to which Eko told her he was "just told to".

As the two set out, under the guise of finding Henry, Eko follows Locke's map and it leads them to the Beechcraft, where they make camp for the night. Locke has a dream, that he is Eko, and climbs the side of the cliff, and then falls to the ground. It is then that Eko climbs the cliff, and spots the question mark salted into the earth, and underneath they find the Pearl station.
| Wipe the stars out of your eyes, sweetheart

What he gets, it a vision from Boone who pushes him through the Sydney Airport in his wheelchair. Locke spots Kate and Sawyer waiting in the security line, and Sawyer says "Wipe the stars out of your eyes, sweetheart...watch and learn little lady".

Later, when Charlie and Locke returned to the camp with Eko, Locke delivered the speech that Desmond had referenced earlier.
