Was Vasudeva Possibly Hallucinating

“Vasudeva saw that wonderful child born as a baby with four hands, holding conchshell, club, disc, and lotus flower, decorated with the mark of Shrivatsa, wearing the jeweled necklace of kaustubha stone, dressed in yellow silk, appearing dazzling like a bright blackish cloud, wearing a helmet bedecked with the vaidurya stone, valuable bracelets, earrings and similar other ornaments all over His body and an abundance of hair on His head.” (Krishna, The Supreme Personality of Godhead, Vol 1, Ch 3)
