A tweet posted late Saturday night by actor Amitabh Bachchan is sending shivers up social media"s spine. At a little before midnight, Bachchan wrote about feeling a sense of unease, tweeting in Hindi: "Na jaane kyun, ek ajeeb si ghabrahat ho rahi hain." His disquiet is now being seen by Twitter as an eerie premonition - hours later, the world learnt that actress Sridevi had died of a cardiac arrest in Dubai, where she and the family were attending a wedding.

Sridevi, who was just 54, was Bachchan"s co-star in the films Inquilaab, Aakhree Raasta and Khuda Gawah. Amitabh Bachchan also made a special appearance in 2012"s English Vinglish, the film that marked Sridevi"s return to screen after a hiatus of many years.

The tweet has left everyone a little perplexed and the explanation of the remark can either be that he was informed about the untimely death of the actress by her family members or he had a premonition. Twitter, Facebook went abuzz with celebrities, fans conveying their shock and tributes to the late Sridevi. From PM Narendra Modi to Kamal Haasan, Rajinikanth, Priyanka Chopra, everybody had something to say about the news which nobody could initially believe.

The comments thread on Amitabh Bachchan"s tweet is full of responses from fans informing him of his former co-star"s death. "Talk about sixth sense," reads one post.

At the time of her death, Sridevi was with her husband Boney Kapoor and daughter Janhvi Kapoor. The actress was attending the marriage of her nephew Mohit Marwah in Dubai where the entire Kapoor family, with the sole exception of Jhanvi Kapoor, was present. The actress suffered a massive cardiac arrest. She was 54.
