Ufologist Ivan Castillo apparently reported that a woman had seen "an object land on a mountain."
One year later, on an unspecified date of 1977, in Lerida, Spain, late in the night, this woman was alone in her bedroom, when a humanoid character, almost 7 feet tall, suddenly appeared, walking towards her.
Terrified, she hid under the blankets, and felt a heavy weight fall on her. She started to scram and the humanoid apparently disappeared.
Albert Rosales indicates in his catalogue that in Lerida, Spain, on 1977, late in the night, a year before, the witness had seen an object land on top of a mountain. On this night she was alone in her bedroom when an almost 7-foot tall humanoid figure suddenly appeared walking toward her. Terrified she hid under the blankets, and felt a heavy weight fall on her. She began to scream and the humanoid apparently disappeared.
Albert Rosales indicates that the source is Ivan Castillo, Aņo Cero.
He comments that the connection with the earlier UFO sighting is tentative, and that this type of bedroom encounter where a tall heavy set humanoid assaults a witness has been reported before and since. He suggests: could it be related to the sleep paralysis syndrome?
Points to consider:
As rightfully pointed by Albert Rosales, the UFO sighting a year before the bedroom visitor experience should not be viewed as related in the strict sense of the term. Besides, seeing "an object land on a mountain" hardly constitute a sighting of high strangeness, and no information exists about it to discard any type of possible confusion. A link however can be that the sighting impressed the witness enough to have an impact of her thoughts during sleep and become the imaginary material of the hypnagogic hallucination she probably experienced - not one item of the report gives the least reason to think that it was not an hypnagogic hallucination and sleep paralysis episode, quite the contrary.
