Previous bull markets

I got into crypto less than a year ago so I just saw the dark side of it, regarding prices. Now it is said that we are at the beginning of a bull market and I was wondering how the previous one behaved. We are seeing a pull back in prices for all major coins. Was like this before? I know that bitcoin is the first and then altcoins will follow. How was it, how was the timing? To those of you that were here in previous bull markets do you recognise a pattern? What do you think will be a time schedule of this cycle? I thought that once a bull run started euforia will create instant surges in prices but I keep seeing fear everywhere that prices will drop. Can some experienced crypto trader help me understand what to expect, until when?
